Answer:
1. Efficiency
2. Kinetic energy
3. Pulley
4. Screw
5. Wedge
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.
