A child with the mass 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.

The child has a greater momentum than the bike

When comparing the momentum of two moving objects, which of the following is correct?

The less massive object will have less momentum if the velocities are the same

A baseball is pitched very fast. Another baseball of equal mass is pitched very slowly. Which of the fallowing statements is correct?

The fast-moving baseball is harder to stop because it has more momentum

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 coster

is greater down the hill than up the hill

A person sitting in a chair with wheel stands, causing the chair to roll backwards across the floor. The momentum of the chair

was zero with stationary and increased when a person stood

A student walks to class of velocity of 3 m/s

while dodging the opening door

An ice skater initially skating at a velocity of 3 m/s speeds up to a velocity of 5 m/s. The momentum of the skater

increases

If force is exerted on an object, which statement is true?

A small force is applied over a long time interval can produce a large change in the object’s momentum

The change in an object’s momentum is equal to

the product of the force applied to the object and the time interval

A force is applied to stop moving a shopping cart. Increasing the time interval over which the force is applied

requires a smaller force

Which of the following situations is an example of visible change in momentum?

a baseball is hit by a bat

Which of the following situations is an example of change in momentum?

A tennis ball hit into a net

The impulse experienced by a body is equivalent to the body’s change in

momentum

A moderate force will break an egg one

the time intevcal for stopping is greater

Which of the following statements properly relates the variables in the equation Ftriangle=triangleP?

a large constant force acting over a long time interval causes a large change in momentum

A large moving ball collides with a small stationary ball. The momentum

of the large ball decreases, and the momentum of the small ball increases

a 75 kg and 80 kg person one

decreased

a 20 kg shopping cart moving at a velocity of 0.5 m/s collides into a store wall and stops. The magnitude of the shopping cart

decreases

A rubber ball moving at a speed of 5 m/s hit a flat wall returned to the thrower at 5 m/s/ The magnitude of the momentum of the rubber ball

remained the same

Two objects with different masses collide and bounce back after an elastic collision. Before the collision, the two objects were moving at a velocities equal in a magnitude but opposite in direction. After the collision,

the less massive object had gained momentum

Two skaters stand facing each other, one is 60 kg and other is 72kg

their momentum are equal but opposite

Two swimmers relax close to each other on air mattresses in a pool. One swimmer’s mass is 48 kg, and the other’s mass is 55 kg. If the swimmers push away from each other,

their momentum are equal but opposite

remains constant

is zero

in a two-body collision,

momentum is conserved

The law of conservation of momentum states that
