The stress-strain curve is a graphical representation of the relationship between stress (force per unit area) and strain (deformation per unit length) in a material. It is fundamental in materials science and mechanical engineering for understanding material behaviour under loading conditions.

Friction is a force that resists the relative motion between two surfaces in contact. Static and kinetic friction are its two primary types, defined based on the state of motion of the objects:

Uniform circular motion plays a key role in understanding rotational dynamics and many real-world phenomena involving circular trajectories.

Newton's laws of motion are three fundamental principles that form the foundation of classical mechanics. They describe the relationship between the motion of an object and the forces acting on it.
