Label the mass-spring system diagram.
1: Mass (m), 2: Spring (k), 3: Equilibrium position.
Label the simple pendulum diagram.
1: Length (L), 2: Mass (m), 3: Angle of displacement ($\theta$).
What is Simple Harmonic Motion (SHM)?
Periodic motion where the restoring force is proportional to the displacement from equilibrium.
Define 'restoring force' in SHM.
The force that always directs toward the equilibrium position and is proportional to the displacement ($F = -kx$).
What is 'amplitude' (A) in the context of SHM?
The maximum displacement of the object from its equilibrium position.
Define 'angular frequency' ($\omega$) in SHM.
A measure of how rapidly the oscillations occur, related to the period (T) by $\omega = \frac{2\pi}{T}$.
What is the 'period' (T) of SHM?
The time it takes for one complete cycle of the motion.
Define 'phase angle' ($\phi$) in SHM.
It represents the initial position of the oscillating object at time t=0.
What is the effect of increasing the mass (m) on the period (T) of a mass-spring system?
Increasing the mass increases the period (T).
What is the effect of increasing the spring constant (k) on the period (T) of a mass-spring system?
Increasing the spring constant decreases the period (T).
What is the effect of increasing the length (L) on the period (T) of a simple pendulum?
Increasing the length increases the period (T).
What is the effect of increasing the gravitational acceleration (g) on the period (T) of a simple pendulum?
Increasing gravitational acceleration decreases the period (T).
What happens to the velocity of an object in SHM as it passes through the equilibrium position?
The velocity is at its maximum value.
What happens to the acceleration of an object in SHM at maximum displacement?
The acceleration is at its maximum value and directed towards the equilibrium position.
