all the equations for Physics

P = V x I.             Power = Voltage x Current.

V = I x R.      Voltage = Current x Resistance.

Q = I x t.                   Charge = Current x time.

E = V x Q.               Energy = Voltage x Charge.

Total cost = number of units x cost per unit.

               Efficiency (%) = (useful energy out ÷ total energy in) x 100.

GPE = mgh.           Gravitational Potential Energy = mass x gravity x height.

   KE  =  ½mv².      Kinetic Energy = 0·5 x mass x velocity².

W = F x d.            Work done = Force x distance.

W = E.              Work done = Energy transferred.

P = E ÷ t.                      Power = Energy ÷ time.

s = d ÷ t.                       speed = distance ÷ time.

p = m x v.              momentum = mass x velocity.

       v = f x l.     wave speed  =  frequency  x  wavelength.

F = m x a.                Force = mass x acceleration.

w = m x g.                      weight = mass x gravity.

         a = (v-u) ÷ t.      acceleration = change in velocity ÷ time.
