Front

What is the definition of velocity?

Back

Velocity is speed in a given direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the difference between speed and velocity?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

If a car travels 150 km in 3 hours, what is its speed?

Back

Speed = 150 km / 3 hr = 50 km/hr.

Front

What do you need to know to calculate velocity?

Back

You need to know both speed and direction.
