The relationship between acceleration, velocity change and the time taken for the change is given by this formula. \(\text{acceleration}=\frac{\text{change in velocity}}{\text{time taken}}=\ ...

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used.

The animation above shows the acceleration to be strictly in the y-direction, as expected. The rate of change of speed is the projection of this acceleration vector onto the unit tangent direction. We ...
