Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.

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 is the unit of momentum?

Back

The unit of momentum is kg m/s.

Front

If a 50 kg ball rolls at 5 m/s, what is its momentum?

Back

250 kg*m/s.

Front

What factors affect momentum?

Back

Momentum depends on an object's mass and 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 (conservation of momentum).

Front

What is the relationship between mass and velocity in momentum?

Back

Momentum increases with either an increase in mass or an increase in velocity.

Front

If two skaters push off each other, what can be said about their speeds?

Back

The skater with the smaller mass will have a greater speed after the push.

Front

What is the principle of conservation of momentum?

Back

The principle states that the total momentum of a closed system remains constant if no external forces act on it.

Front

What is an example of momentum in everyday life?

Back

A moving car has momentum; if it stops suddenly, its momentum is transferred to the passengers.
