Momentum Practice - AP Physics 1

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event (like a collision or explosion) is equal to the total momentum after the event.

Front

How does mass affect stopping time when braking force is constant?

Back

If the braking force is constant, a car with double the mass will take twice the time to stop compared to a car with half the mass, assuming the same initial speed.

Front

What happens to kinetic energy during an explosion in space?

Back

Kinetic energy is not conserved in an explosion; however, the total momentum of the system is conserved.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

Front

How do you calculate the change in momentum?

Back

Change in momentum can be calculated using the formula Δp = mv_final - mv_initial.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass × Acceleration (F = ma).

Front

What is the effect of friction on the motion of an object?

Back

Friction opposes the motion of an object, causing it to decelerate and eventually stop.

Front

How do you determine the direction of impulse?

Back

The direction of impulse is the same as the direction of the net force applied to the object.

Front

What is the formula for calculating force using impulse?

Back

Force can be calculated using the formula F = Δp / Δt, where Δp is the change in momentum and Δt is the time interval.
