What is the definition of Period (T)?

The time it takes for one complete cycle or oscillation, measured in seconds (s).

What is the definition of Frequency (f)?

The number of cycles or oscillations per second, measured in Hertz (Hz), where 1 Hz = 1 s⁻¹.

Define spring constant (k).

A measure of the stiffness of a spring. Higher k means a stiffer spring.

What is a simple pendulum?

A mass (bob) hanging from a string of length (L), swinging back and forth.

Define Simple Harmonic Motion (SHM).

Motion that oscillates or repeats itself, such as a swing, spring, or pendulum.

Label the following diagram of a mass-spring system.

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.
