Momentum

Front

What is momentum?

Back

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

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What are the units of momentum?

Back

The units of momentum are kilogram-meters per second (kg-m/s).

Front

If a cart has a mass of 0.250 kg and is moving at 0.400 m/s, what is its momentum?

Back

0.1 kg-m/s.

Front

What two factors does momentum depend on?

Back

Momentum depends on mass and velocity.

Front

What happens to momentum when the speed of an object is doubled?

Back

When the speed of an object is doubled, its momentum also doubles.

Front

What is the relationship between force and momentum?

Back

The net force acting on an object is equal to the rate of change of its momentum.

Front

What is the formula for calculating net force?

Back

Net force (F) can be calculated using F = ma, where m is mass and a is acceleration.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is an example of momentum in everyday life?

Back

A moving car has momentum due to its mass and speed.
