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.

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 ...

Speed of a body is the distance travelled by it per unit time and Velocity of a body is the distance travelled by it per unit time in a given direction. This article deals with why Speed and Velocity ...

One must get the methods of measuring position and time working together if we are to obtain a reliable representation of motion. To that end we have developed a unique system composed of elements ...
