Define Simple Harmonic Motion (SHM).
A special type of periodic motion where the restoring force is directly proportional to the displacement.
What is periodic motion?
Motion that repeats in a regular cycle over time.
Define the period (T) of an oscillation.
The time it takes to complete one full cycle.
Define the frequency (f) of an oscillation.
The number of cycles per unit time, measured in Hertz (Hz).
What is a restoring force?
A force that always acts to bring an object back to its equilibrium position.
Define equilibrium position.
The point where the net force on an object is zero, resulting in zero acceleration.
What is Simple Harmonic Motion (SHM)?
A special type of periodic motion where an object moves back and forth repeatedly around a central equilibrium point due to a restoring force.
Define 'restoring force' in the context of SHM.
A force that always points towards the equilibrium position, pulling the object back to its center.
What is the 'equilibrium position' in SHM?
The position where the net force on the object is zero, resulting in zero acceleration.
Define 'amplitude' in the context of SHM.
The maximum displacement of the object from its equilibrium position during oscillation.
What is the 'period' (T) of SHM?
The time required for one complete oscillation or cycle of the motion.
What is the 'frequency' (f) of SHM?
The number of oscillations per unit of time, usually measured in Hertz (Hz).
What happens when an object is displaced from equilibrium in SHM?
The restoring force pushes or pulls it back towards the equilibrium position.
What is the effect of increasing the displacement from equilibrium on the restoring force?
The restoring force increases linearly.
What happens to the total mechanical energy in SHM?
The total mechanical energy (potential + kinetic) is conserved; energy is constantly exchanged between potential and kinetic forms.
What happens if the mass in a mass-spring system is doubled?
The period of oscillation increases by a factor of .
What happens if the length of a pendulum is quadrupled?
The period of oscillation is doubled.
