Determine for each of the following statements whether it is always true or can be false.-Two objects of same mass and moving at the same velocity have the same momentum.-In a perfectly inelastic collision, some of the kinetic energy is lost.-Momentum of a system is not conserved when the mechanical energy is not conserved. If the objects have different masses, then these equal forces will produce different accelerations. The momentum of an object can change. However, the momentum of an individual object is altered as momentum is transferred between colliding objects. c. FALSE - An object which is traveling east could encounter a collision from the side, from behind (by a faster-moving object) or from the front. Momentum depends upon the variables mass and velocity. When substituted into the N•s expression, the result is the kg m/s. Thus, m is defined to be the rest mass, which could be … The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. The velocity change of two respective objects involved in a collision will always be equal. True or False? An object that has mass but no velocity will not have momentum. True Momentum is not equal to the mass of an object divided by its velocity. When an action and reaction occurs, momentum is usually lost True or false? False. when a firecracker bursts, the vector some of the momentum of its fragments add up to the firecrackers momentum just before bursting. An object which experiences a net impulse will definitely experience a momentum change. Net Force (and Acceleration) Ranking Tasks, Trajectory - Horizontally Launched Projectiles, Which One Doesn't Belong? Momentum is not a form of energy. An object that travels to the left and speeds up has a momentum to the right. a. If an object is traveling eastward, then it has an eastward momentum. An object which is moving at a constant speed has momentum. Momentum depends upon two quantities * mass and velocity. Direction does not matter when you are measuring momentum. g. TRUE - In a collision, there is a collision force which endures for some amount of time to cause an impulse. Same momentum, different velocities - - Two bodies with same linear momentum but different masses have different velocities. Momentum can be transferred from one object to another. Impulse is a quantity which depends upon both force and time to change the momentum of an object. i. b. The kg•m/s is equivalent to the units on impulse. _____5.) The Newton can be written as a kg•m/s^2. i. In a collision between two objects of identical mass, the acceleration values could be different. f. TRUE - The N•s is the unit of momentum.

A force of 100 N acting for 0.1 seconds would provide an equivalent impulse as a force of 5 N acting for 2.0 seconds. A moving air track glider collides with a second stationary glider of identical mass. The combination of force and time is what is referred to as an impulse. FALSE - No. So we can easily deduce that momentum is directly proportional to velocity of an object if the mass of the object remains constant. True _1.) The momentum of an object can change. ... All objects have mass; so if an object is moving, then it has momentum. In a perfectly inelastic collision (as it is sometimes called), the two colliding objects stick together and move as a single unit after the collision. 5. Now an object with a lot of momentum must have such a mass AND such a velocity that the product of the mass and velocity is relatively large. 2. A moving object collides with a stationary object; the stationary object has significantly less mass. b. All moving objects don’t have momentum. True.

The linear momentum of an object is proportional to the mass of the object. if two objects of different mass have the same momentum, then the object with the least mass needs to have a greater velocity . Answer True Or False. _____6. Two objects of varying mass have the same momentum. 30 seconds . The One With The Largest Mass Has The Smallest Momentum. The relativistically correct definition of momentum as p = γmu is sometimes taken to imply that mass varies with velocity: m var = γm, particularly in older textbooks.However, note that m is the mass of the object as measured by a person at rest relative to the object. There are no exceptions to this rule. FALSE - In any collision, the colliding objects will experience equal (and opposite) momentum changes, provided that the collision occurs in an isolated system. c.

However, one should be quick to note that the object does not have to have a constant speed in order to have momentum. 80. ___10.) Two objects with the same mass will always have the same momentum. answer choices . chamric3205 is waiting for your help. False. TRUE - For the same speed (and thus velocity), a more massive object has a greater product of mass and velocity; it therefore has more momentum. ____8.) c. FALSE - The impulse encountered by an object is equal to mass multiplied by velocity change - that is, momentum change. 1 momentum is not equal to the mass of an object divided by its velocity. A moving object collides with a stationary object; the stationary object has significantly less mass. Misconception Alert: Relativistic Mass and Momentum. Momentum is not equal to the mass of an object divided by its velocity. Two identical objects are moving in opposite directions at the same speed. TRUE - A perfectly elastic collision is a collision in which the total kinetic energy of the system of colliding objects is conserved. FALSE - Few collisions are completely elastic. l. FALSE - In any collision, the colliding objects will experience equal (and opposite) momentum changes, provided that the collision occurs in an isolated system. answer choices . When that inertia is in motion, the object has momentum. b. And objects only warm up (converting mechanical energy into thermal energy) when their surfaces meet and atoms at those surfaces are set into vibrational motion or some kind of motion. Momentum is conserved in an elastic collision but not in an inelastic collision. When an object speeds up, it gains momentum. 4.) This is simply Newton's law of action-reaction. The momentum of an object can change. 2000 kg m/sec. Momentum is momentum and energy is energy. If it is moving, then it has kinetic energy. 11.) Objects with different masses can’t have the same momentum. true statements. The vector sum of the momentum is the same before and after a collision. 4. _____2. It is momentum which is conserved by an isolated system of two or more objects. The linear momentum of an object is proportional to the mass of the object. TRUE - There is significant bounce in the collision between a tennis racket and tennis ball. 3.) Elastic collisions occur when the collision force is a non-contact force. T. 5. 30 seconds . All moving objects don’t have momentum. Therefore, object A will also have more kinetic energy. ___3.) h. FALSE - Total momentum is conserved only if the collision can be considered isolated from the influence of net external forces. Momentum worksheet name true or false. Which of the following statements are true about momentum? 30 seconds . Before the collision, all the kinetic energy is in the first glider. Object A clearly has more momentum. Most collisions are not inelastic because the collision forces cause energy of motion to be transformed into sound, light and thermal energy (to name a few). 3.9 kg. If two particles of different masses have equal kinetic energy they also have equal momentum. TRUE - Impulse is a vector quantity Like momentum, impulse is not fully described unless a direction is associated with it. FALSE - The Joule is the unit of work and energy. As such, the second glider has the kinetic energy which the first glider once had. _____ 1. After the collision, the first glider has no kinetic energy; yet the second glider has the same mass and velocity as the first glider. Find an answer to your question “How can two objects of different masses have the same momentum ...” in SAT if the answers seem to be not correct or there’s no answer. Part A: Determine whether the following statements are true or false. A ball is dropped from rest and collides with the ground. Answer: A, C, and D Momentum can be thought of as mass in motion. Sound is only produced when atoms of one object make contact with atoms of another object. _____ 2. All moving objects don’t have momentum. This 10 N•s impulse is equivalent to the impulse created by a force of 5 N for 2.0 seconds. The momentum of an object can change. The kg m/s is the standard unit of momentum. Momentum of any object is defined as the multiple of velocity of an object and the mass of the object. TRUE - For the same speed (and thus velocity), a more massive object has a greater product of mass and velocity; it therefore has more momentum. 3. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. - Formula is Linear momentum(p) = Mass(m) × Velocity(v) - Momentum have same direction as that of velocity. c. FALSE - Momentum can be conserved in both elastic and inelastic collisions provided that the system of colliding objects is isolated from the influence of net external forces. Get an answer to your question “Two objects with different masses and different velocities have the same momentum. g. TRUE - Momentum is calculated as the product of mass and velocity. There is typically little bounce in the collision between a halfback and a linebacker (though there are certainly exceptions to this one). Momentum is not equal to the mass of an object divided by its velocity. If two objects of different masses have same momentum, the lighter body possess greater velocity. An object with a changing speed will have a changing momentum. The higher that the ball rises upon collision with the ground, the more elastic that the collision is. While individual objects may change their velocity during a collision, the overall or total velocity of the colliding objects is conserved. F. 4. Objects involved in collisions encounter impulses. An object has momentum if it has its mass in motion. True. 3. _____3. The forward moving object will have the greatest momentum. _____1.) h. TRUE - Yes!!! a.Momentum is a vector quantity. _____3. Momentum DRAFT. _____4. © 1996-2021 The Physics Classroom, All rights reserved. _____5. e. FALSE - This statement is mistaking the term velocity for momentum. Momentum is NOT a form of energy; it is simply a quantity which proves to be useful in the analysis of situations involving forces and impulses. Momentum requires mass AND velocity. a.

The One With The Highest Velocity Has The Higher Momentum. Which of the following are true about the relationship between momentum end energy? An object can be traveling eastward and slowing down; its momentum is westward. The impulse encountered by an object in a collision causes and is equal to the momentum change experienced by that object. The direction of the impulse is dependent upon the direction of the force exerted upon the object. Two colliding objects will exert equal forces upon each other even if their mass is significantly different. It matters not whether the object is of large mass or small mass, moving with constant speed or accelerating; if the object is MOVING, then it has momentum! d.An object which is moving at a constant speed has momentum. It is kinetic energy that is conserved in a perfectly elastic collision. TRUE - Momentum is a vector quantity. Terms in this set (18) The total momentum of an isolated system of objects is conserved regardless of the nature of the forces between the objects.
