Define Simple Harmonic Motion (SHM).
Oscillations where the restoring force is directly proportional to the displacement from equilibrium.
Define 'Period' (T) in SHM.
The time it takes for one complete oscillation, measured in seconds (s).
Define 'Frequency' (f) in SHM.
The number of complete oscillations per second, measured in Hertz (Hz).
Define 'Angular Frequency' (ω) in SHM.
The rate of change of the angle in radians per second, measured in rad/s.
Define 'Restoring Force'.
The force that brings an object back to its equilibrium position.

What is the effect of increasing the mass in a spring-mass system on its period?
The period increases.
What happens to the period of a simple pendulum if its length is doubled?
The period increases by a factor of √2.
What is the effect of increasing the spring constant on the period of a spring-mass system?
The period decreases.
What happens to the period of a simple pendulum if the acceleration due to gravity increases?
The period decreases.
What is the effect of increasing frequency on the period?
The period decreases.
