Chapter 5.1, Problem 1CP

Interpretation Introduction

Interpretation:

The kinetic energy of a mass moving at given velocity is to be calculated.

Concept introduction:

Energy is defined as the capacity to do work or transfer heat.

Kinetic energy is the energy created from the motion of an object.

Kinetic energy is given by the expression below.

$E_k=\frac{1}{2}m{u}^2$

Here, m is the mass and u is the velocity of the object.

The S.I. unit of kinetic energy is joule (J).

$1\text{J}$ is equal to 1 $\text{kg}{\text{.m}}^{\text{2}}{\text{/s}}^{\text{2}}$

CConversion factor is $\frac{1\text{J}}{\text{kg}{\text{.m}}^{\text{2}}{\text{/s}}^{\text{2}}}$
