Physics Formulae Start Of Yr12

Velocity

Velocity

= displacement/time v = s/t

Acceleration

= change in velocity/time a = ^v/^t

Acceleration

= (final - initial velocity)/time a = (v-u)/t

Resultant force

= mass x acceleration F =ma

Weight

= mass x gravitational field strength W=mg

Kinetic Energy

= ½ x mass x speed² KE= ½ mv²

Change in GPE

= mass x GFS x change in height EGRAV = mg^h

Momentum

= mass x velocity p=mv

Force

= rate of change of momentum F=^(mv)/t

Pressure

= force/area p=f/a

Work done

= average force x distance moved in the direction of the force W=f^s

Current

= charge/time I=q/t

Voltage

= current x resistance V = IR

Voltage

= energy/charge or work/charge V = E/Q or W/Q

Power

= current x voltag

Power

= energy/time P = E/T

Energy

= power x time E = Pt

Energy

= current x voltage x time E = VIt

Wave speed

= frequency x wavelength v = f w

Change in energy

= speed of light² x change in mass ^E = c² ^m
