A:
How can we deduce the units of energy from the definition of kinetic
energy?
The kinetic energy is the energy required to move any mass m with velocity v. In other word work required to move any body.
In mathematically, it is half of product of mass and square of velocity. That is,
Using equation of motion,
Since body start from rest, so
So force required
So work done, to move object
So the kinetic energy is,
So unit,
