Practice Other Topics from Work and Energy
In this topic, we will learn the concept of work. Units and formulas of work are also discussed here. We will come to know about different instances when the work is said to be done.
This topic briefly explains the energy with the help of an activity. It mentions the different forms of energy. It explains how work can be done against gravity. It also discusses measuring units of energy and their conversion.
Through this topic, we will learn about mechanical energy and its different forms. It explains the kinetic and potential energies, their different forms, examples, and formulae. It also discusses the law of conservation of energy.
In this topic, we will learn about the time rate at which work is done or energy is transferred i.e. power. It also explains its SI unit, and derivation of formula along with instantaneous power.
This topic highlights different sources of energy. It discusses renewable and non-renewable sources with examples. It explains solar, heat, light, chemical, hydro, and wind energies. It also describes the sound, magnetic, and nuclear energy.
