Periodic motion where the restoring force is proportional to the displacement, like a mass on a spring.

The energy of motion, dependent on mass and velocity.

Stored energy, dependent on position relative to the equilibrium point.

The point where the net force is zero.

The maximum displacement from the equilibrium position.

The potential energy stored in a spring, given by $\frac{1}{2}kx^2$, where k is the spring constant and x is the displacement.

Kinetic Energy: Energy of motion, maximum at equilibrium. | Potential Energy: Stored energy, maximum at extreme positions.

Maximum Kinetic Energy: Occurs at equilibrium, velocity is maximum. | Maximum Potential Energy: Occurs at extreme positions, velocity is zero.

Kinetic energy: Energy of motion, maximum at equilibrium. Potential energy: Stored energy, maximum at maximum displacement.

Maximum velocity: Occurs at the equilibrium position. Maximum displacement: Occurs at the amplitude (farthest point from equilibrium).
