Motion Graphs

Front

What is a displacement-time graph?

Back

A graph that shows the distance of an object from a reference point over time.

Front

What does a straight line on a displacement-time graph indicate?

Back

Uniform velocity, meaning the object is moving at a constant speed.

Front

What does a horizontal line on a displacement-time graph represent?

Back

The object is at rest; there is no change in displacement over time.

Front

What does a curve on a displacement-time graph signify?

Back

The object is accelerating or decelerating; the speed is changing.

Front

What is uniform velocity?

Back

When an object covers equal distances in equal intervals of time.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What does a negative slope on a displacement-time graph indicate?

Back

The object is moving back towards the starting point.

Front

How can you tell if one object overtakes another on a displacement-time graph?

Back

If the graph of one object crosses the graph of another object.

Front

What does it mean if an object is slowing down?

Back

The object's speed is decreasing over time.

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).
