Momentum and Impulse Review - Honors 2025

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula 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, calculated as Impulse = Force × Time.

Front

How does increasing the time of impact affect force?

Back

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

Front

Can two objects with different masses have the same momentum?

Back

Yes, two objects can have the same momentum if they have different masses and velocities that compensate for each other.

Front

What is the principle of conservation of momentum?

Back

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

Front

What happens to the momentum of a system when an external force acts on it?

Back

The momentum of the system changes, as external forces can alter the total momentum.

Front

What is the relationship between mass, velocity, and momentum?

Back

Momentum is directly proportional to both mass and velocity; increasing either will increase momentum.

Front

How does a baseball player's glove technique reduce impact force?

Back

By moving the glove backward, the player increases the time of impact, which reduces the force experienced.

Front

What is the effect of rain accumulating in a moving cart on its speed?

Back

The speed of the cart decreases due to the conservation of momentum as the mass of the cart increases with the added rain.

Front

What is the formula for calculating momentum?

Back

The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.
