Momentum and Impulse

Front

What does the law of conservation of momentum state?

Back

The total momentum before an event is the same as the total momentum after the event.

Front

What happens to impulse and force when an egg lands on a soft surface?

Back

The soft surface increases the time and decreases the force during the impact.

Front

What remains constant in any collision?

Back

Total Momentum.

Front

What are the standard metric units of impulse?

Back

Newton * second.

Front

Why does a cannon recoil when it fires a cannonball?

Back

This occurs because momentum in the system is conserved.

Front

Define momentum.

Back

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

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 related to force and time?

Back

Impulse = Force × Time.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = Mass (m) × Velocity (v).

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.
