A thermometer is a device used to measure temperature. It operates on the principle of thermal expansion of liquids or changes in electrical resistance. Common types include mercury thermometers alcohol thermometers and digital thermometers. Thermometers are widely used in weather ...
The kinetic theory of matter explains that matter is made up of tiny particles in constant motion. These particles collide with each other and the walls of their container, resulting in pressure and temperature. The theory describes the relationship between ...
The coefficient of restitution is a dimensionless value that measures the elasticity of a collision between two bodies. It is the ratio of relative velocity after impact to relative velocity before impact. Represented by ‘e,’ it ranges from 0 (perfectly ...
Displacement is a vector quantity that measures the shortest straight-line distance between an object’s initial and final positions. It includes both magnitude and direction, distinguishing it from distance. Displacement is essential in motion analysis as it represents the change in ...
