Label the following diagram of a simple pendulum.
1: String, 2: Bob, 3: Length (L)
What is the effect of increasing the mass on a spring-mass system?
Increases the period of oscillation.
What is the effect of increasing the spring constant in a spring-mass system?
Decreases the period of oscillation.
What is the effect of increasing the length of a simple pendulum?
Increases the period of oscillation.
What is the effect of increasing gravity on a simple pendulum?
Decreases the period of oscillation.
What happens to the period if the frequency increases?
The period decreases.
What happens to the frequency if the period decreases?
The frequency increases.
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.
