Please explain work and kinetic and potential energy?
Work is said to be done when a body or object moves with the application of external force.
Work=Force×Displacement=F.d Let’s take an example. When we kick a football, we are exerting an external force called F, and due to this force (kick), the ball moves to a certain distance. This disposition of ball from position A to B is known as displacement (d). This work is said to be done and can be calculated as w = F.d
The capacity to do work is called as Energy. This energy can be stored in different forms. Energy is one of the physical quantities as it is proportional to the mass of the object. The ability of the body to exert a push or a pull against the natural forces like the gravity identifies as to what kind of energy is it. When an object is at rest, the body is said to possess potential energy. In another case, when the object is in motion, then it is said to possess kinetic energy.
Potential energy tends to affect the object within the environment if and only when it gets transformed into other kinds of energy. A rock which rests at the top of cliff said to be an example of the body possessing potential energy. When the rock falls, it possesses kinetic energy. The energy which is stored in a body because of the elevation is called as gravitational potential energy. Some bodies like waterfalls contain both kinetic as well as potential energy. The height of the waterfall is one of the basis for potential energy, while the movement of water is a base for the kinetic energy.
The property of body decides as to what kind of energy is contained in it. The Potential energy changes into kinetic energy when an object moves. Unlike the potential energy, the kinetic energy can be transferred from one body to another body by the process of collision.
The difference between these two kinds of energies are as explained below-
Differences Between Kinetic and Potential Energy Sr.no Kinetic Energy Potential Energy 1. Kinetic energy is the kind of energy present in a body due to the property of its motion Potential Energy is the type of energy present in a body due to the property of its state 2. It can be easily transferred from one body to another It is not transferable 3. The determining factors for kinetic energy are Speed or velocity and mass Here, the determining factors are Height/ distance and mass 4. Flowing water is one of the examples of kinetic energy Water present at the top of hill is an example of potential energy 5. It is relative with respect to nature It is non-relative with respect to nature
