Impulse-Momentum Flashcard

Front

What is the impulse-momentum theorem?

Back

The impulse-momentum theorem states that the change in momentum of an object is equal to the impulse applied to it.

Front

Define momentum in physics.

Back

Momentum is defined as the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (p) is p = m * v, where m is mass and v is velocity.

Front

What is the SI unit of momentum?

Back

The SI unit of momentum is kg·m/s.

Front

How does increasing collision time affect the force experienced during a collision?

Back

Increasing collision time reduces the force experienced during a collision, as force is inversely proportional to time when impulse is constant.

Front

What factors affect the momentum of an object?

Back

The momentum of an object is affected by its mass and velocity.

Front

Explain why a bowling ball requires more force to catch than a ping pong ball.

Back

A bowling ball requires more force to catch than a ping pong ball because it has a greater mass and therefore more momentum.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object.

Front

How can momentum be conserved in a closed system?

Back

In a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event, assuming no external forces act on it.

Front

What is the effect of mass on momentum?

Back

As mass increases, momentum increases if velocity remains constant.
