Distance and Time Graphs and Basic Motion/Force

Front

What does a distance-time graph show?

Back

A distance-time graph shows how the distance of an object changes over time.

Front

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

Back

A horizontal line indicates that the object is not moving.

Front

What is acceleration?

Back

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

Front

If you make a right turn while walking, what happens to your velocity?

Back

Your velocity changes because you are changing direction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

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

Back

The slope represents the speed of the object.

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).

Front

What is meant by 'constant speed'?

Back

Constant speed means that an object covers equal distances in equal intervals of time.

Front

How can you determine the greatest speed on a distance-time graph?

Back

The greatest speed is indicated by the steepest slope on the graph.

Front

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

Back

A steep slope indicates a high speed.
