1 Time 10 swings, human error Density of a liquid Volume (cm3)
General Physics Time Length stopwatch Pendulum Ruler Measuring Cylinder V = L xW x h Time 10 swings, human error Density of a liquid Volume (cm3) Density of a stone V2-V1 Divide time by 10 Density of a rectangular cube Density =Mass(g)/volume (cm3)

2 Force- earth pulls to the center
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

3 Moment in clock.=moment in anti-clock.
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

4 Watt is the unit of power???
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???
