- 1. Multiple Choice
When comparing the momentum of two moving objects, which of the following is correct?
the object with the higher velocity will have less momentum if the masses are equal
the more massive object will have less momentum if its velocity is greater
the less massive object will have less momentum if the velocities are the same
the more massive object will have less momentum if the velocities are the same
- 2. Multiple Choice
A child with a mass of 23 kg rides a bike with a mass of 5.5 kg at a velocity of 4.5 m/s to the south. Compare the momentum of the child with the momentum of the bike.
Both the child and the bike have the same momentum
the bike has a greater momentum than the child
the child has a greater momentum than the bike
neither the child nor the bike has momentum
- 3. Multiple Choice
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
is greater up the hill than down the hill
is greater down the hill than up the hill
remains the same throughout the ride
is zero throughout the ride
- 4. Multiple Choice
If a force is exerted on an object, which statement is true?
a large force always produces a large change in the object's momentum
a large force produces a large change in the object's momentum only if the force is applied over a very short time interval
a small force applied over a long time interval can produce a large change in the object's momentum
a small force produces a large change in the object's momentum
- 5. Multiple Choice
The impulse experienced by a body is equivalent to the body's change in
velocity
kinetic energy
momentum
force
- 6. Multiple Choice
A 75 kg person walking around a corner bumped into an 80 kg person who was running around the same corner. The momentum of the 80 kg person
increased
decreased
remained the same
was conserved
- 7. Multiple Choice
Two skaters stand facing each other. One skater's mass is 60 kg, and the other's mass is 72 kg. If the skaters push away from each other without spinning,
the lighter skater has lees momentum
their momenta are equal but opposite
their total momentum doubles
their total momentum decreases
- 8. Multiple Choice
In a two-body collision,
momentum is always conserved
kinetic energy is always conserved
neither momentum nor kinetic energy is conserved
both momentum and kinetic energy are always conserved
- 9. Multiple Choice
The law of conservation of momentum states that
the total initial momentum of all objects interacting with one another usually equals the total final momentum
the total initial momentum of all objects interacting with one another does not equal the total final momentum
the total momentum of all objects interacting with one another is zero
the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects

a hare with a mass of 2.7 kg moving at a velocity of 7.5 m/s
a turtle with a mass of 91 kg moving at a velocity of 1.4 m/s
a roadrunner with a mass of 1.8 kg moving at a velocity of 6.7 m/s
- 11. Multiple Choice
A person sitting in a chair with wheels stands up, causing the chair to roll backward across the floor. The momentum of the chair
was zero while stationary and increased when the person stood
was greatest while the person sat in the chair
remained the same
was zero when the person got out of the chair and increased while the person sat
- 12. Multiple Choice
Two objects with different masses collide and bounce back after an elastic collision. Before the collision, the two objects were moving at velocities equal in magnitude but opposite in direction. After the collision,
the less massive object had gained momentum
the more massive object had gained momentum
both objects had the same momentum
both objects lost momentum
