full explanation of work, energy and machines

Explanation:
HEY MATE ..
Work can be defined as transfer of energy. In physics we say that work is done on an object when you transfer energy to that object.
If one object transfers (gives) energy to a second object, then the first object does work on the second object. Work-
Energy Principle --The change in the kinetic energy of an object is equal to the net work done on the object. Energy can be defined as the capacity for doing work.
The simplest case of mechanical work is when an object is standing still and we force it to move.
The energy of a moving object is called kinetic energy. For an object of mass m, moving with velocity of magnitude v, this energy can be calculated from the formula E= 1/2 mv^2.
Types of Energy:
There are two types of energy in many forms:Kinetic Energy = Energy of MotionPotential Energy = Stored Energy
A machine is a thing that is created by people to make work easier. It is a tool or invention which multiplies the effect of human effort. The machine produces a mechanical advantage. ... Often a machine will change one form of energy to another form of energy. Simple machines increase or change the direction of a force.

Answer:
work and energy are both the same
Explanation:
work=force x distance
Energy is also force x distance
Energy is also defined as the ability to do work and work is the transfer of energy from one body to the other in order to make the 2nd object move
when it comes to machines they are the device that exhibits motion
