## kinetic energyEnergy of motion, equivalent to one-half an object's mass multiplied by its velocity squared. If a body of mass m has an initial velocity u and is accelerated
by a constant force F to velocity of v then from Newton's
laws of motion, v^{ 2} = u^{ 2} +
2as and the definition of force F = ma, then
the work done is equal to Fs.
If the body starts from rest, u = 0 and so the work done on it
would be ½mv^{ 2}. This gives the amount of energy
that any moving body of mass m traveling at velocity v
has. Compare with potential energy. ## Related category• CLASSICAL MECHANICS | |||||
