Momentum Flashcard

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 the product of force and time (Impulse = Force × Time).

Front

How does impulse relate to momentum?

Back

Impulse is equal to the change in momentum of an object. If an object experiences an impulse, its momentum changes by that amount.

Front

What is the principle of conservation of momentum?

Back

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

Front

What is an elastic collision?

Back

An elastic collision is a collision in which both momentum and kinetic energy are conserved.

Front

What is a perfectly inelastic collision?

Back

A perfectly inelastic collision is a type of collision where the two objects stick together after colliding, resulting in maximum kinetic energy loss.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg*m/s).

Front

If two objects have the same momentum, what can be said about their mass and velocity?

Back

If two objects have the same momentum, their mass and velocity are inversely related; if one object's mass increases, its velocity must decrease to maintain the same momentum.

Front

What happens to momentum in a closed system during a collision?

Back

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