Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, Einstein!

Calculate the velocity using the formula: velocity = distance ... the effect of varying force or mass on the acceleration of an object for GCSE physics and combined science. This short film ...

The theory predicts a cause for reaction acceleration: due to the balls colliding, a force is applied to the interface of the reactants, where the product is formed. This force reduces the ...

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.
