Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It ...

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 ...

Speed-time graphs are very useful when describing the movement of an object. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area ...
