formulas

F=ma

net force= mass (kg) x acceleration (m/s²)

KE= ½ mv²

Kinetic Energy (joules)= ½ mass (kg) velocity (m/s)

W=FD

work (nm)= force x displacement (joules)

nm= joules

P= W/T

power (watts)= work (joules)/ sec

PEg= mgh

Potential Energy (joules) = mass gravity height

f= 1/T

frequency (Hz)= 1/ Period (seconds)

v= d/t

wave speed= distance/ time

v= fλ

wave speed= frequency (Hz) x λ (wavelength)

q= Ne

Q (Electric Charge) (coulombs) = N(# of electrons) x e (fundamental charge)

FE= KE (q1*q2/r²)

Fe- electrostatic force
Ke- Coulumbs Constant
q1- charge body 1 (C). q2- charge body 2 (C)
r= shortest distance between the 2 charges (m)

V= J/C

Electrical Potential (voltage)= Joule/ Coulomb

I= q/t

Electric current (ampere) = Charge (coulomb)/ time (Sec)

V= R *I

ohms law: Voltage= Resistance (ohms) * Current (ampere)

P= VI

Electric Power (watts)= Voltage x Current (ampere)
