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 = mass (m) × velocity (v).

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time. It is equal to the product of the force and the time duration.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum for a given velocity. Momentum is directly proportional to mass.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum for a given mass. Momentum is directly proportional to velocity.

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 conserved.

Front

Can momentum be transferred between objects?

Back

Yes, momentum can be transferred from one object to another during collisions.

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 when two objects collide?

Back

The total momentum of the two objects before the collision is equal to the total momentum after the collision.
