Question

What types of potential energy are included in the work energy equation?

		All forms of potential energy
		Elastic potential energy only
		Gravitational and elastic energy only
		Gravitational energy only

Answer 1

Solution)

Answer is 3rd option' Gravitational and Elastic Energy only.

In work energy equation including a spring,  gravitational and elastic potential energy are considered.

============

Answer 2

 The correct answer is:

(c) Gravitational and elastic energy only

Explanation:

The work-energy equation (also known as the work-energy principle) accounts for the change in kinetic energy and includes contributions from:

• Gravitational Potential Energy ($U_g$Ug) – due to an object's position in a gravitational field.

• Elastic Potential Energy ($U_e$Ue) – due to deformation of elastic objects like springs.

The general form of the work-energy equation is:

$$W_{\text{net}} = \Delta K + \Delta U_g + \Delta U_e$$

Other forms of potential energy (such as chemical or electric potential energy) are not typically included in the standard work-energy equation in classical mechanics.

Answer 3

The correct answer is:-

                             Gravitational and elastic energy only

Explanation:-

The work-energy equation considers the conversion between kinetic energy and potential energy. The potential energy types included are:

• Gravitational potential energy: $U = mgh$

• Elastic potential energy: $U = \frac{1}{2} kx^2$

Other forms of potential energy (like chemical or electrical) are not explicitly included in the basic work-energy theorem.
