Momentum Concepts and Calculations

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 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, momentum is transferred between the colliding objects, but the total momentum of the system remains the same.

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.

Front

How does mass affect momentum?

Back

An increase in mass will result in a proportional increase in momentum if velocity remains constant.

Front

How does velocity affect momentum?

Back

An increase in velocity will result in a proportional increase in momentum if mass remains constant.

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

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 impulse = force × time.

Front

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum of an object, represented by the equation impulse = Δp.
