Momentum Basics

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 are the units of momentum?

Back

The units of momentum are kg·m/s.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity because it has both magnitude and direction.

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv, where p is momentum, m is mass, and v is velocity.

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

Give an example of momentum in sports.

Back

In sports, a football player running with the ball has momentum, which affects their ability to be tackled.

Front

What is the relationship between mass and momentum?

Back

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

Front

What is the relationship between velocity and momentum?

Back

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