Question

Explain the difference between the slope of a distance-time graph for a fast-moving object and the slope of a distance-time graph for a slower moving object.

Answer 1

A sloping line on a distance-time graph shows that the object is moving. In a distance-time graph, the slope or gradient of the line is equal to the speed of the object. The steeper the line (and the greater the gradient) the faster the object is moving.

Answer 2

The fast moving object would have a steeper slope going up, because the distance it is traveling is farther, making it go higher on the graph. The slower moving object would have a more gradual slope, because it is not going as high for the the time it is traveling.
