NOTATION

Quantities in formulas

Elastic force is a force that occurs when a body deforms.
The stiffness of a spring is a characteristic of its resistance to deformation.
Elongation is a change in the length of a body during deformation.
Potential energy is the energy of the relative position of bodies or parts of a system.
A period is the time of one complete repetition of a process.
Mass is a scalar physical quantity that is a measure of the inertia of a body.
