What is the formula for momentum?
p = m * v
p = m - v
p = m / v
p = m + v
In a perfectly elastic collision, which of the following is conserved?
Kinetic energy only
Momentum only
Total energy and momentum
Momentum and kinetic energy
If two objects collide and stick together, what type of collision is this?
Perfectly elastic collision
Inelastic collision
Superelastic collision
Elastic collision
What happens to the total momentum of a system in a closed system during a collision?
The total momentum of a system is conserved during a collision in a closed system.
The total momentum increases during a collision.
Momentum is not affected by collisions in a closed system.
The total momentum decreases during a collision.
Which of the following quantities is a vector?
Time
Speed
Velocity
Distance
In a two-dimensional collision, how is momentum conserved?
Momentum is lost during a two-dimensional collision.
Momentum is conserved only if the objects stick together.
Momentum is only conserved in the x direction.
Momentum is conserved in both the x and y directions during a two-dimensional collision.
What is the impulse experienced by an object?
Impulse is the product of force and the time duration over which it acts.
Impulse is the change in velocity divided by time.
Impulse is the total mass of the object.
Impulse is the energy transferred to the object.
If a 2 kg object moving at 3 m/s collides with a stationary 1 kg object, what is the final velocity of the 1 kg object after a perfectly elastic collision?
5 m/s
4 m/s
2 m/s
3 m/s
What is the relationship between impulse and momentum?
Impulse is equal to the change in momentum.
Impulse is unrelated to momentum.
Momentum causes impulse to increase.
Impulse is the same as momentum.
In a collision, if object A has a greater mass than object B, which object will experience a greater change in velocity?
Object B will experience a greater change in velocity.
Neither object will experience any change in velocity.
Object A will experience a greater change in velocity.
Both objects will experience the same change in velocity.
