Do both objects experience the same change in momentum?
Yes. The two objects experience the same force (NIII) and impact time, so they have the same impulse. Impulse equals the change in momentum, so the two objects have the same change in momentum.
Can two objects have the same momentum but different masses?
The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.
Can 2 objects of significantly different masses have the same kinetic energy?
Kinetic energy is a function of mass and velocity, so objects of different masses can have the same kinetic energy.
What happens if 2 objects have the same speed but different velocities?
Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. They represent objects that have different velocities only because they are moving in different directions.
Can two objects with different masses have the same momentum and kinetic energy simultaneously?
No. If their masses differ then they will not have the same momentum.
When comparing the momentum of two moving objects which statement is always correct?
The more massive object will have less momentum if the velocities are the same. 4. A roller coaster climbs up a hill at 4 m/s and then zips down the hill at 30 m/s. The momentum of the roller coaster: A. is greater up the hill than down the hill.
What will be the percentage change in momentum of a body when both its mass and velocity are doubled?
Momentum of a body of given mass, is directly proportiional to its velocity. When momentum is doubled, mass remaining constant, this means velcity is doubled. Hence, kinetic energy becomes 22=4 times i.e. say from 100 units to 400 units. and percentage increase in kinetic energy is 400−100=300\% .
