what is energy?write difference from of energy.also write the formula for calculating kinetic energy and potential energy
Answers
Explanation:
The capacity to do work is called 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 gravity identifies as to what kind of energy it is. 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.
Difference 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 a hill is an example of potential energy
5. It is relative with respect to nature It is non-relative with respect to nature
energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
P.E. = mgh
K.E. = 1/2 m v2
