Correct option is C
Energy is defined as the
capacity to do work. In physics, energy enables an object or system to perform work, which involves the application of force over a distance. Energy exists in various forms such as mechanical, thermal, chemical, and electrical energy. Work is done when energy is transferred from one form to another or from one object to another.
Forms of Energy:
Kinetic Energy: Energy of a moving object, given by KE = 1/2 mv2.
Potential Energy: Energy due to an object's position, given by PE = mgh.
Units of Energy: The SI unit of energy is the joule (J), where 1 joule equals 1 Newton-meter ( Nm ).
