A distance-time graph shows how the distance an object travels changes over time. Speed is equal to the value of the _________ of the line on a distance-time graph. If the slope is flat, the object’s speed is ____________. If the slope is shallow, the object’s speed is _________. If the slope is steep, the object’s speed is _________. Which terms, in order of appearance, best complete the sentences about distance-time graphs?

• slope; slower; zero; faster

• slope; zero; slower; faster

• x-axis; faster; zero; slower

• y-axis; zero; faster; slower

Look at the image of a slinky on the top of a staircase. When a slinky is put at the top of the staircase and the top is flipped to the next step, energy will be transferred in a longitudinal wave. This type of motion will help the slinky continuously move down from one stair step to the next until it reaches the bottom. Which of the following steps is needed to create a distance-time graph? How would you interpret the speed from a distance-time graph?

• Measure the distance covered at regular time intervals and plot the points.

• Count the number of steps the slinky takes to reach the bottom.

• Record the time taken for the slinky to reach the bottom only.

• Calculate the potential energy at each step.

A runner completes a race and the distance-time graph is plotted. What does a horizontal line on this graph indicate about the runner's motion?

• The runner is moving at a constant speed.

• The runner is accelerating.

• The runner is stationary.

• The runner is decelerating.

Consider a distance-time graph of a train journey. If the graph shows a steep slope followed by a flat line, what can be inferred about the train's motion?

• The train is speeding up and then stops.

• The train is moving at a constant speed and then accelerates.

• The train is slowing down and then moves at a constant speed.

• The train is moving at a constant speed and then stops.
