Force of gravity Amount of matter Force- earth pulls to the center Mass Weight Kg Newton (N) Always stays the same Changes Weight = mg = mass x 10
F = ma Fᾳ x F=kx Hooke’s Law Forces Shape, size and motion Moment = fxd equilibrium Moment in clock.=moment in anti-clock. No resultant force and turning effect
Joules(J) Energy potential Kinetic Work W = fxd P.E =mgh • KE=½ mv2 • PEtop =Kebottom • mgh= ½ mv2 • gh=1/2 v2 • v2= 2gh • v= 2gh P=W/t Watt is the unit of power???
