Density =Mass(g)/volume (cm3)

Density of a liquid

Density of a stoneV2-V1 Density of

a rectangular

cube

Mass

Newton (N)Always stays the

same

Amount of matter

WeightKg

Force of gravity

Force- earth pulls

to the center

Weight = mg= mass x 10

Forces

Hooke’s Law

Shape, size and motion

Fᾳ xF=kx

F = ma

Moment in clock.=mome

nt in anti-clock.No resultant

force and turning effect

Moment = fxd

equilibrium

Energy

WorkW = fxd

P=W/t

Kinetic

PEtop =Kebottom

mgh = ½ mv2

gh=1/2 v2

v2 = 2gh v= 2gh

P.E =mgh

potential

KE=½ mv2

Joules(J)

Watt is the unit of power???
