Front

How does the direction of momentum relate to velocity?

Back

The direction of the momentum vector depends on the direction of the velocity vector.

Front

What is a system in the context of physics?

Back

A system is a definite collection of particles in a defined space.

Front

What are external forces?

Back

External forces are forces that occur from outside the system.

How do you calculate the momentum of an object?

Back

Front

If an object has a mass of 10 kg and a velocity of 5 m/s, what is its momentum?

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event, according to the law of conservation of momentum.

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.
