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.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum, assuming the velocity remains constant.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum, assuming the mass remains constant.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg m/s).

Front

If two objects have the same mass, how does their momentum compare if one is moving faster?

Back

The object moving faster will have greater momentum than the object moving slower.

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 (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.

Front

How can you increase the momentum of an object?

Back

You can increase the momentum of an object by increasing its mass, increasing its velocity, or both.

Front

What is the relationship between momentum and force?

Back

Force is the rate of change of momentum; a greater force results in a greater change in momentum over time.
