Front

When an object’s distance from another object is changing, what is it doing?

Back

It is in motion.

Front

Total distance divided by total time is known as?

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

What does acceleration measure?

Back

The rate of change of velocity over time.
