A distance-time graph shows how the distance travelled by an object changes over time and can be used to calculate the speed of the object. A sloping line on a distance-time graph shows that the ...

In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

The speed of a body gives us an idea of how slow or fast that body is moving. For example if a car is running slow, we say that its speed is low. And if a car is running fast, then we say that its ...
