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 ...

Instead, they strongly suggest that there is local acceleration near 5.5 Re, and that radial diffusion actually transports electrons away from the Earth, beyond the radiation belts. In contrast to ...

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.
