Physics Equations

Weight(N)= Mass(Kg) x Strength of Gravity(N/Kg)

W= M G

Density= Mass/Volume

p= M/V

Pressure= Force/ Area

p= F/A

Pressure in Liquid= Depth x Denisty x Strength of Gravity

Force= Spring Constant x Extension

F= K E

Turning Moment= Force x Distance

M= F D

Distance= Speed x Time

D= S T

Acceleration= Change in velocity / Time

a= (v-u)/t

Force= Mass x Acceleration

F= M A

Momentum = Mass x Velocity

p= m v

Power = Energy Transfered/ Time

p= e/t

Power= Work done/ Time

P= W/T

Efficiency= Useful energy Output/ Total energy Input

Wavespeed= Frequency x Length

Charge Flow= Current x Time

Q= I T

Potential difference= Current x Resistance

V= I R

Power= Potential difference x Current

P= V I

Power= Current squared x Resistance

P= I(squared) x R

Energy Transferred= Power x time

E= P T

Energy Transferred= Charge Flow x Potential Difference

E= Q I
