Back

50 mi/hr.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes direction.

Front

What does acceleration mean in terms of motion?

Back

Acceleration is the rate of change of velocity over time.

Front

What is a reference point in motion?

Back

A reference point is a stationary object used to determine the position of another object.

Front

What does a horizontal line on a distance vs. time graph indicate?

Back
