Unit 5


Force (F) and siplacement (s)

  • Force and displacement (distance moved from a point) are vectors meaning that they have a direction as well as size
  • The direction matters as the force and the distance moved must be in the same direction 

The equation work done = force x distance moved in teh same direction applies

w=F(change in)s

Force equations

gpe=mg(change in)h      Gravitational potential energy= mass x gravity (9.8) x change in height 

Ke= 1/2mv^2 …
