Chapter 6, Problem 6RQ

Interpretation Introduction

Interpretation:

Change in total, kinetic and potential energy is to be described, as the spring moves from its lowest point to its highest point and its difference from the pendulum used in the previous question is to be interpreted.

Concept Introduction:

According to the law of conservation of mass energy can neither be created nor be destroyed. It is conserved in different forms of energies.

The spring suspended from the fixed point implies that there cannot be any scope of altering this end of the spring. However, the other end is stretched and its configuration change makes energies to vary.

A pendulum is a hanging instrument from a solid and static suspension.

The kinetic energy of an object is due to its motion in the favor of or against the forces of attraction or repulsion. 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 potential energy is gained by virtue of attractive or repulsive forces acting from distance apart. Potential energy is given by expression: $\text{P}\text{.E}=m\times \text{g}\times h$. Here, $m$ is the mass of the object, $\text{g}$ is the gravitational constant and $h$ is the height
