Speed - Time Graphs

Front

What type of speed does a graph with a downward slope represent?

Back

Decreasing Speed

Front

What is the equation for calculating speed?

Back

speed = distance/time

Front

What does a graph showing a straight line at an angle indicate?

Back

Constant Speed

Front

What does a graph with a steep upward slope represent?

Back

Acceleration (speeding up)

Front

If an object is at rest, what does its speed graph look like?

Back

The line is completely flat.

Front

How do you calculate the speed of an object?

Back

Speed is calculated by dividing the distance traveled by the time taken.

Front

What happens to the slope of a speed-time graph if the object slows down?

Back

The line is less steep.

Front

If Reese runs 10 meters in 5 seconds, what is her speed?

Back

2 meters/sec

Front

What does a horizontal line on a speed-time graph indicate?

Back

The object is moving at a constant speed.

Front

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

Back

The object is decelerating (slowing down).
