Chapter 10, Problem 1A

Interpretation Introduction

Interpretation:The difference between kinetic and potential energy needs to be determined.

Concept introduction: Energy is defined as the ability to do work or to produce heat. Energy is classified as kinetic energy and potential energy.

Answer to Problem 1A

The potential energy of a system solely depends on the composition or position of the system. While kinetic energy depends on the motion of the object.

Explanation of Solution

Potential energy is the energy that takes place due to the position or the composition such as water behind a dam has the potential energy. This energy can be converted to work due to flow of water through the turbines which results in electricity production.

Kinetic energy of an object is the energy due to the motion of the object and it depends on the mass of the object m and the velocity v. It is given as,

  $\text{KE}=\frac{1}{2}m{v}^2$

Conclusion

Energy is classified as kinetic energy and potential energy. Potential energy depends on the position and composition and kinetic energy depends on the motion of the object.
