Calculating Average Speed

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What type of graph shows distance over time?

Back

A distance/time graph.

Front

What does a flat line on a distance/time graph indicate?

Back

The object is not moving.

Front

If a car travels 300 miles in 5 hours, what is its average speed?

Back

60 mph.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What does a negative acceleration indicate?

Back

The object is slowing down.

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 speed/time graph represent?

Back

It shows how speed changes over time.
