## Important Topics for HC Verma Solutions for Class 11 Physics Chapter 8 -Work and Energy

Kinetic Energy

In physics, the kinetic energy of an object refers to the energy that it owns due to its motion. It is described as the work needed to increase the speed of a body of a certain mass from rest to its stated velocity. Having to increase this energy during its acceleration, the body preserves this kinetic energy unless its speed changes.

Potential Energy

The energy that an object contains because of its location relative to other objects, pressures within itself, its electric charge, or other factors is known as potential energy.

Work-energy Theorem

The work-energy theorem is also called the principle of work and kinetic energy. The theorem states that the work done by the addition of all forces acting on an element equals the change in the kinetic energy of the element. The formula for total work is total work = change in kinetic energy = final kinetic energy – initial kinetic energy.

Conservative and Non-conservative Forces

A force where the total work is done in moving an element from one point to another is independent of the taken path is known as the conservative force. Consistently, if an element travels in a closed-loop, the complete work done by a conservative force is zero.

Non-Conservative forces are defined as the forces where the work is done or the kinetic energy does depend on other factors such as the velocity or the specific path taken by the item.

Gravitational Potential Energy

Gravitational potential energy is the energy a body owns because of its location in a gravitational field. The most common use of gravitational potential energy is for a body near the surface of the Earth where the gravitational acceleration can be expected to be continuous at about 9.8 m/s2.

Conservation of Mechanical Energy

The complete amount of mechanical energy in a locked system in the lack of dissipative forces remains constant. This shows that potential energy can turn into kinetic energy or vice versa, but energy cannot “disappear”.
