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 = mass (m) × velocity (v).

Front

What is the unit of momentum?

Back

The unit for momentum is kg m/s.

Front

Is momentum a scalar or vector quantity?

Back

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

Front

What happens to the momentum of an object if its velocity is zero?

Back

If an object's velocity is zero, its momentum is also zero.

Front

Calculate the momentum of a 1000-kg car moving at 20 m/s north.

Back

20000 kg m/s north.

Front

If a 0.250 kg cart moves southwest at 0.400 m/s, what is its momentum?

Back

0.1 kg m/s southwest.

Front

What is the relationship between mass and momentum?

Back

Momentum increases with an increase in mass if velocity remains constant.

Front

What is the relationship between velocity and momentum?

Back

Momentum increases with an increase in velocity if mass remains constant.

Front

Can momentum change without a change in mass?

Back

Yes, momentum can change if there is a change in velocity.
