Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

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 type of quantity is momentum?

Back

Momentum is a vector quantity.

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 an elastic collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not.

Front

Which has more momentum: a moving train or a stationary car?

Back

A moving train has more momentum than a stationary car because momentum depends on velocity.

Front

If two objects collide and stick together, what type of collision is it?

Back

It is an inelastic collision.

Front

What is the relationship between mass and momentum?

Back

Momentum increases with an increase in mass if velocity remains constant.

Front

What is the relationship between velocity and momentum?

Back

Momentum increases with an increase in velocity if mass remains constant.
