Equations

Forces, motion and energy · SI units

Resultant force	F = ma
Acceleration	a = (v − u) / t
Final velocity	v = u + at
Displacement	s = ut + ½at²
Velocity and distance	v² = u² + 2as
Weight	W = mg
Work done	E = Fd
Kinetic energy	Eₖ = ½mv²
Gravitational potential energy	Eₚ = mgh
Power	P = E / t

u: initial velocity · v: final velocity · a: acceleration · t: time · s/d: displacement · m: mass · g: gravitational field strength. Constant-acceleration equations assume uniform acceleration; work equation assumes a force parallel to displacement.
