The gradient of a displacement-time graph at a particular time gives the velocity of the object at that time. The gradient of a velocity-time graph at a particular time gives the acceleration of the ...

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...

Physicists use the displacement formula to find an object's change in position. It sounds simple, but calculating displacement can quickly get complicated. Let's break it down using some solved ...
