Momentum Intro Concept Flashcard 2024

Front

What symbol represents impulse according to the AP physics equation sheet?

Back

Front

What happens to the momentum of an object when its speed is doubled?

Back

The momentum of the object doubles.

Front

If two objects have the same momentum, how can one have more kinetic energy than the other?

Back

An object can have more kinetic energy if it has more speed than the other object.

Front

What is the effect of extending the time of a collision?

Back

Extending the time of a collision decreases the peak force experienced during the collision.

Front

What is the purpose of crumple zones in cars?

Back

Crumple zones are designed to increase the time of impact, thereby reducing the force experienced by occupants.

Front

Define momentum in physics.

Front

What is the relationship between impulse and momentum?

Back

Front

How does mass affect momentum?

Back

For a constant velocity, an increase in mass results in an increase in momentum.

Front

What is the formula for calculating kinetic energy?

Back

Front

Explain the concept of conservation of momentum.

Back

The conservation of momentum states that in a closed system, the total momentum before an event is equal to the total momentum after the event.
