Distance vs. Time and Speed Vs. Time Graphs

Front

What does a distance vs. time graph represent?

Back

It shows how the distance of an object changes over time.

Front

What does a speed vs. time graph represent?

Back

It shows how the speed of an object changes over time.

Front

What does it mean if a graph is a straight line?

Back

The object is moving at a constant speed.

Front

What does a curve in a distance vs. time graph indicate?

Back

The object is accelerating or decelerating.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its speed.

Front

What does negative acceleration mean?

Back

It means the object is slowing down.

Front

What does it mean if the speed vs. time graph is horizontal?

Back

The object is moving at a constant speed.

Front

What does it mean if the speed vs. time graph slopes downwards?

Back

The object is decelerating.

Front

What does it mean if the speed vs. time graph slopes upwards?

Back

The object is accelerating.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
