Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

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 conserved.

Front

What is a completely inelastic collision?

Back

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

Front

How does mass affect momentum?

Back

Momentum increases with mass; a more massive object will have more momentum if both objects are moving at the same velocity.

Front

How does velocity affect momentum?

Back

Momentum increases with velocity; an object moving faster will have more momentum if both objects have the same mass.

Front

What is the law of conservation of momentum?

Back

The law of conservation of momentum states that in a closed system, the total momentum before and after a collision remains constant.

Front

What happens to momentum in a collision?

Back

In a collision, the total momentum of the system (all objects involved) before the collision is equal to the total momentum after the collision.

Front

Can a small car have more momentum than a big truck?

Back

Yes, if the small car is moving significantly faster than the big truck, it can have more momentum despite its smaller mass.

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.
