MECHANICS AND PROPERTIES OF MATTER
Mechanics explains how objects move and interact under the action of forces, while properties of matter describe the various ways materials respond to external influences such as force, heat, and pressure. Both topics form the foundation of classical physics and help us understand everything from planets in motion to everyday materials and fluids.

Mechanics and Properties of Matter – FAQ
Mechanics is a branch of physics that deals with the motion of objects and the forces acting on them. It includes both statics (bodies at rest) and dynamics (bodies in motion).
Mechanics is mainly divided into two types: Classical Mechanics (based on Newton’s laws of motion) and Quantum Mechanics (for microscopic particles). Classical mechanics further includes statics, kinematics, and dynamics.
Properties of matter describe how substances behave under various conditions. It includes elasticity, viscosity, plasticity, surface tension, and fluid dynamics.
Elasticity is the property of a material to regain its original shape after deformation. Hooke’s Law states that the strain in a material is directly proportional to the applied stress within the elastic limit.
Surface tension is the property of a liquid that makes its surface act like a stretched elastic membrane. It results from cohesive forces between liquid molecules at the surface.
Viscosity is a measure of a fluid’s resistance to flow. A highly viscous fluid (like honey) flows more slowly than a low-viscosity fluid (like water).
