Chapter 2, Problem 2.17E

Interpretation Introduction

Interpretation:

To verify the equation 2.8

Concept introduction:

The work is performed on an object when an object moves a certain distance s due to the force F. Mathematically, it is indicated by the dot product of the force vector F and the distance vector s. The mathematical equation is given below,

$Work=F\cdot s= \left|F\right|\left|s\right|cos\theta$

Where $\theta$ is the angle between the vectors F and s. The unit of work is joules. Work is a way to transfer the energy. The energy is defined as the ability to do work and so energy and work are described using the same unit in joules.
