Speed/Motion

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

Which would NOT make a good reference point?

Back

A moving child.

Front

What is happening at D?

Back

Fast steady speed; moving away from the starting position.

Front

What is the formula to calculate speed?

Back

S = d/t.

Front

What is happening at A?

Back

Stationary (At rest).

Front

Define speed.

Back

Speed is the distance traveled per unit of time.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s).

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 a flat line on a distance-time graph represent?

Back

It represents an object that is stationary.

Front

What does a steeper slope on a distance-time graph indicate?

Back

It indicates a higher speed.
