Period

Unit
Period is here the duration of a harmonic oscillation. In the case of a spring pendulum, it is the duration of the oscillation until the mass reaches the same deflection again.

Mass

Unit
Mass of the body that performs a harmonic oscillation. It can be, for example, a piece of mass on a vibrating spring.

Spring constant

Unit
Spring constant describes the stiffness of a spring, that is how well the spring can be deflected.
