Stress is the internal restoring force per unit area developed in a material when subjected to an external force. It quantifies the material’s ability to resist deformation. Stress is measured in Pascals (Pa) and can be categorized into tensile compressive ...

A mechanical spring-ball system demonstrates energy storage and transfer. The spring stores potential energy when compressed or stretched which is released to propel the ball. This principle is widely used in toys mechanical systems and energy-absorbing devices to convert stored ...
Elasticity: Elasticity is the property of a material to regain its original shape and size after the removal of applied force. It obeys Hooke’s Law within the elastic limit. Plasticity: Plasticity is the property of a material to undergo permanent ...
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 ...
