Explanation:

1. Efficiency: the ratio of work output to work input or the ratio of actual mechanical advantage (AMA) to ideal mechanical advantage (IMA).

Mathematically, the efficiency of a machine is given by the formula;

2. Kinetic energy: the energy of a moving object. Kinetic energy (KE) is an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

3. Pulley: a grooved wheel over which a rope can move. It is made up of a wheel and rope which allows force to be multiplied such as in a drawing well.

4. Screw: a double-sided inclined plane. It is held in position and then used to tighten two or more objects together.

5. Wedge: an inclined plane wrapped around a cylinder. It can be used to split objects into halves.

the part of the wave he is travelling on is the crest

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
