Question

prove the formula K.E.=1/2mv2

Answer 1

Answer:

The work done is accelerating an object is given by:

W=FΔx

Where,

F is the force and

Δx the displacement.

If the object started from rest and all of the work was converted to kinetic energy then this will be equal to the kinetic energy of the object.

Find the below attachment...

so K simplifies to:

K=mv²/2
