Front

A change in speed and/or direction is called what?

Back

Acceleration.

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / 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).

What does a speed-time graph represent?

Back

It shows how speed changes over time.

Front

What does a flat line on a speed-time graph indicate?

Back
