Momentum and Impulse

Front

What is the equation to calculate momentum?

Back

p = mv

Front

What does the Law of Conservation of Momentum state?

Back

The total momentum before a collision is equal to the total momentum after a collision.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

How is impulse calculated?

Back

Impulse = Force × Time

Front

What happens to momentum in a closed system during a collision?

Back

Momentum is conserved.

Front

What is the relationship between force and acceleration?

Back

Force = Mass × Acceleration (F = ma)

Front

What is the effect of a larger mass on momentum?

Back

A larger mass results in greater momentum if velocity is constant.

Front

If two objects collide, what can be said about the forces they exert on each other?

Back

The forces are equal in magnitude and opposite in direction (Newton's Third Law).

Front

What is the formula for calculating impulse?

Back

Impulse = Change in Momentum = Final Momentum - Initial Momentum

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, kinetic energy is conserved; in inelastic collisions, kinetic energy is not conserved.
