Question:

The kinetic energy KE of an object of mass m moving with velocity v is defined as KE = 1/2 mv2. If a force f(x) acts on the object, moving it along the x-axis from x1 to x2, the Work-Energy Theorem states that the net work done is equal to the change in kinetic energy: 1/2 mv22 – 1/2 mv21, where ν1 is the velocity at x1 and ν2 is the velocity at x2.
