Front

What variable goes on the y-axis of a distance-time graph?

Back

Distance

Front

Which graph shows an object slowing down?

Back

Graph E

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula to calculate average speed?

Back

Average Speed = Total Distance / Total Time

Front

If a turtle is crawling at 34 cm/min, what type of measurement is this?

Back

Speed

Front

What happens to the motion of a ball thrown vertically upward?

Back

The ball slows down as it goes up to the peak and then speeds up as it falls.

Front

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

Back

It represents that the object is at rest.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s) or kilometers per hour (km/h)

Front

If a car travels 150 kilometers in 3 hours, what is its average speed?

Back

50 km/h

Front

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

Back

It indicates a higher speed.
