12/3 Speed and Graphs

Front

What is speed?

Back

Speed is the distance traveled by an object divided by the time it took to travel that distance.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that shows equal distance covered in equal time intervals.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s).

Front

If a cheetah runs 280 meters in 10 seconds, what is its speed?

Back

28 meters per second.

Front

What is average speed?

Back

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

Front

What is the average speed of a toy car that travels 240 cm in 60 seconds?

Back

4 centimeters per second.

Front

What does the slope of a distance-time graph represent?

Back

The slope represents the speed of the object.

Front

If an object travels 5.1 meters in 7 seconds, what is its speed?

Back

Speed = 5.1 m / 7 s = 0.73 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).
