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 ...
A frictionless inclined table is a smooth surface tilted at an angle to the horizontal, where no frictional force opposes motion. Objects on the table move solely under the influence of gravity and normal force. It simplifies calculations in physics ...
Velocity is a vector quantity that describes the rate of change of an object’s position with respect to time. It includes both speed and direction, distinguishing it from scalar speed. Measured in meters per second, velocity is a key parameter ...
Restitution refers to the process of restoring an object to its original state after deformation or impact. In physics it is often used to describe the coefficient of restitution which measures the elasticity of collisions between two bodies indicating how ...
Velocity is a vector quantity that refers to the rate at which an object changes its position. It has both magnitude and direction, expressed as displacement per unit time. Commonly measured in meters per second (m/s), velocity provides crucial information ...
Lubricated refers to the application of a substance, like oil or grease, to reduce friction between surfaces in contact, enhancing performance. Class 11 Physics explores Chapter 5, focusing on work, energy and power concepts. It covers definitions, calculations and practical applications ...
