Chapter 6, Problem 3RQ

Interpretation Introduction

Interpretation:

The equation that is used to calculate the kinetic energy of an object is to be stated. The symbols used in the equation are to be defined and the variable that has a larger effect on kinetic energy, when it is doubled, is to be determined.

Concept Introduction:

Energy is intangible in any form. The kinetic energy of an object is due to its motion in the favor of or against the forces of attraction or repulsion. A high kinetic energy implies that the object should move with a comparatively higher speed. The value of kinetic energy depends upon the mass of the object and the speed with which it propels. Mathematically, kinetic energy is $\text{K}\text{.E = }\frac{1}{2}m{v}^2$. Here, $m$ is the mass of the object and $v$ is the velocity of the object.

The mass and velocity of the object are directly proportional to kinetic energy. The more the mass of the object, the more will be the velocity of its motion and the kinetic energy.
