Speed & Motion Graphs

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What unit is speed measured in?

Back

Speed can be measured in meters per second (m/s).

Front

If an object travels 100 meters in 5 seconds, what is its speed?

Back

20 m/s.

Front

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

Back

A flat line represents constant speed.

Front

What does a steep slope on a speed-time graph indicate?

Back

A steep slope indicates a high speed.

Front

What does a downward slope on a speed-time graph represent?

Back

A downward slope represents deceleration or slowing down.

Front

What is acceleration?

Back

Acceleration is the rate of change of speed over 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).
