Momentum

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 the formula for calculating momentum?

Back

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

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

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 an inelastic collision?

Back

An inelastic collision is a collision in which momentum is conserved, but kinetic energy is not.

Front

If a 1000-kg car is moving at 20 m/s, what is its momentum?

Back

The momentum is 20,000 kg*m/s north.

Front

True or False: A big truck will always have more momentum than a small car.

Back

False. Momentum depends on both mass and velocity.

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.

Front

What is the unit of momentum?

Back

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

Front

How does increasing mass affect momentum?

Back

Increasing mass will increase momentum if velocity remains constant.
