Speed =

distance time final velocity - initial velocity Acceleration = change in time

d t v f - vi

Momentum = mass × velocity

Force = mass × acceleration Work = force × distance Power = work time work output × 100 work input 1 mass × velocity 2 2

t p = mv

F = ma

W = Fd W t WO %= ×100 WI P=

% efficiency =

Kinetic energy =

KE =

mv 2 2

Gravitational potential energy = mass × acceleration due to gravity × height Energy = mass × (speed of light )2 Velocity of a wave = frequency × wavelength Current = voltage resistance

GPE = mgh E = mc 2 v = f I= V R

Electrical Power = voltage × current Electrical energy = power × time

P = VI E = Pt

Constants/Conversions

g = acceleration due to gravity = 9.8 m/s 2 c = speed of light = 3 × 10 8 m/s

speed of sound = 343 m/s at 20 C 1 cm 3 = 1 mL 1 wave/second = 1 hertz (Hz) 1 calorie (cal) = 4.18 joules 1000 calories (cal) = 1 Calorie (Cal) = 1 kilocalorie (kcal) newton (N ) = kgm/s 2 Joule (J) = Nm Watt (W) = J/s = Nm/s volt (V) ampere (A) ohm ()
