5.2 Impulse Questions

Front

What happens to the stopping force if the stopping time is increased?

Back

The stopping force decreases.

Front

Stopping an object over a longer period of time will ______ the stopping force.

Back

decrease.

Front

Impulse is the product of force and ______.

Back

time.

Front

What is the formula for impulse (J) in physics?

Back

J = Ft.

Front

What is Newton's 2nd Law of motion?

Back

F = ma.

Front

Define impulse in physics.

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

How does increasing the mass of an object affect its momentum?

Back

Increasing the mass increases the momentum, assuming velocity remains constant.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum (Impulse = Δp).

Front

If a force is applied for a longer time, what happens to the change in momentum?

Back

The change in momentum increases.
