Velocity and Momentum

Front

What does momentum depend on?

Back

Momentum depends on an object's mass and velocity.

Front

Calculate the momentum of a 50 kg ball rolling at 5 m/s.

Back

The momentum is 250 kg*m/s.

Front

What is the formula for average speed?

Back

Average speed = total distance / total time.

Front

If a runner completes a 100 meter dash in 10 seconds, what is her average speed?

Back

Her average speed is 10 m/s.

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What information do you need to calculate speed?

Back

You need the distance traveled and the time taken.

Front

Define velocity.

Back

Velocity is the speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

What is the unit of momentum?

Back

The unit of momentum is kg*m/s.

Front

How do you calculate momentum?

Back

Momentum = mass x velocity.
