Light Energy – definition, properties, examples and uses

A system needs energy to do work. There are various forms of energy that are used for different purposes. Light energy is one of those. Lives on the Earth are highly dependent on the energy of light in many aspects. Sun is the only natural source of light in Earth. We are using sunlight directly … Read more

Conservation of Mechanical Energy of a system

Energy is a basic physical property of a system. Physics defines the energy as the ability to do work. That means a system or a body can do a work only if it has some energy. A system can store energy in many forms like Mechanical energy, Chemical Energy, Electrical energy, etc. Again, energy can … Read more

Calculation of Work done in Physics – formula

Work is one of the popular words in our daily life. The word work means to do something. We need some energy to do a work for us. Physics also says that some external energy is required to do a work. But, the Work done in Physics is different from the work we know in … Read more

Difference between kinetic and potential energy in physics

We already have the concepts of mechanical energy from previous article. There are two types of mechanical energy – Kinetic energy and potential energy. Kinetic energy also has two types – translational kinetic energy and rotational kinetic energy. Read the article on rotational kinetic energy if you need. In this article, I’m going to share … Read more
