Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity.

Front

What is velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the formula for calculating speed?

Front

If a car travels 300 km in 3 hours, what is its average speed?

Back

Average speed = 300 km / 3 hr = 100 km/hr.

Front

What is the difference between speed and velocity?

Back

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

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.
