Momentum Pre-Assessment

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the equation p = mv.

Front

What is the unit of momentum?

Back

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

Front

How does mass affect momentum?

Back

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

Front

How does velocity affect momentum?

Back

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

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

If a car has a mass of 1000 kg and is moving at 20 m/s, what is its momentum?

Back

The momentum is 20000 kg m/s.

Front

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

Back

The bike moving at 15 mph has more momentum.

Front

What is the relationship between momentum and velocity?

Back

Momentum is directly proportional to velocity; as velocity increases, momentum increases.

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 (conservation of momentum).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
