| Question | Answer |
| equation to calculate weight | weight = mass x gravity N kg n/kg |
| equation for work done | work done = force x distance J N meters |
| equation that links force , spring constant and extension | force = spring constant x extension N n/m M |
| contact forces | hitting a ball with a bat |
| non contact forces | gravity , magnetic |
| difference between mass and weight | mass is how much matter an object is made up of and weight is dependant on gravity |
| equation for speed | speed = distance/time m/s m s |
| equation for acceleration | acceleration= (final - initial velocity) ------------------------------ time |
