Kinematics
A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine parts, those two parts experience a relative motion with each other. Studying such relative motions is termed kinematics.
Kinetic Energy and Work-Energy Theorem
In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the direction of displacement and perpendicular to the displacement which is called the normal force. Energy is the capacity of any object doing work. The SI unit of work is joule and energy is Joule. This principle follows the second law of Newton's law of motion where the net force causes the acceleration of an object. The force of gravity which is downward force and the normal force acting on an object which is perpendicular to the object are equal in magnitude but opposite to the direction, so while determining the net force, these two components cancel out. The net force is the horizontal component of the force and in our explanation, we consider everything as frictionless surface since friction should also be calculated while called the work-energy component of the object. The two most basics of energy classification are potential energy and kinetic energy. There are various kinds of kinetic energy like chemical, mechanical, thermal, nuclear, electrical, radiant energy, and so on. The work is done when there is a change in energy and it mainly depends on the application of force and movement of the object. Let us say how much work is needed to lift a 5kg ball 5m high. Work is mathematically represented as Force ×Displacement. So it will be 5kg times the gravitational constant on earth and the distance moved by the object. Wnet=Fnet times Displacement.

The term "energy" comes from the Greek word energeia or from the French words en meaning in and ergon which means work. There are many different types of energy, such as kinetic energy, potential energy, light, sound, and nuclear energy. One form of energy may be converted into another or transferred from one object/substance to another.
KINETIC ENERGY
Kinetic energy is the energy an object possesses due to its motion. Atoms and their components are all in motion, so all matter possesses kinetic energy. An object of mass (m) moving at velocity (v) has a kinetic energy equal to ½mv2 : A common formula for kinetic energy. Kinetic energy is usually denoted by the letter KE in equations. An example of kinetic energy is a swinging pendulum. A typical unit for kinetic energy is the joule.
POTENTIAL ENERGY
Potential energy is that energy which an object has because of its position. It is called potential energy because it has the potential to be converted into other forms of energy, such as kinetic energy. Potential energy is usually denoted by the capital letter U in equations or sometimes by PE.
Potential energy may also refer other forms of stored energy, such as energy from net electrical charge,
POTENTIAL ENERGY EXAMPLES
A ball resting on top of a table has potential energy. This is called gravitational potential energy because its energy the object gains from its vertical position. The more massive an object is, the greater its gravitational potential energy.
A drawn bow and a compressed spring also have potential energy. This is elastic potential energy, which results from stretching or compressing an object. For elastic materials, increasing the amount of stretch raises the amount of stored energy. Springs have energy when stretched or compressed.
Chemical bonds may also have potential energy, as electrons can move closer or further away from atoms. In an electrical system, potential energy is expressed as voltage.
