all equations

all equations???

speed

S = Distance / Time

Acceleration

a = Δvelocity / Δtime

Forces

F = Mass x Acceleration

Weight

W = Mass x Gravitational field strength

Work Done

WD = Force x Distance

Power

P = Δenergy / time

Gravitational Potential Energy

GPE = mass x gravity x height

Kinetic energy

KE = ½ X mass x velocity**2

Density

D = Mass / Volume

Pressure

P = Force / Area

Pressure with depth

P in depth = density x gravity x height

Boyles Law

P1 x V1 = P2 x V2

Heat energy

mass x specific heat x Δtemperature
(mcΔt) (MCAT)

Kelvin

celsius + 273

Frequency

1/T

Wave speed

frequency x wavelength

Refractive index

RI = speed in vacuum / speed in solid

Snells law (refractive index)

sin(angle o incidence)/sin(angle o refraction)

sin (i) / sin (r)

Critical angle

1 / refractive index

Current

Current (I) = charge (Q) / time (t)

Volts

Voltage (V) = energy (E) / charge (Q)

Resistance

Resistance = Voltage (V) / Current (I)

Energy

Energy = Power x Time

Power

Power = Voltage (V) × Current (I)

Charge

Charge = I (Current) x T (time)
