P2.2.1 Forces and energy AQA GCSE Physcics

P2.2.1 Forces and energy - everything you need for this unit

a) When a force causes an object to move through a distance work is done.                                           b) Work done, force and distance are related by the equation:                                                                       W is the work done in joules, J   F is the force applied in newtons, N                                                                              d is the distance moved in the direction of the force in metres, m

c) Energy is transferred when work is done.

the transfer of kinetic energy in particular situations. Examples might include shuttle re-entry or meteorites burning up in the atmosphere.                                                                                                         d) Work done against frictional…
