Absolute zero = 0 K = -273.15 degrees Celsius
The temperature at which atoms or particles of an object have zero kinetic energy or no vibration.
Simple Harmonic Motion (SHM) is the acceleration proportional to the negative displacement.
a = - w^2 x
where: a = acceleration, w = angular frequency, x = displacement from equilibrium position.
For an object oscillating in a simple harmonic motion, acceleration is directly proportional to displacement, and the direction of acceleration is always opposite to the direction of displacement.
Damping is loss of total energy of system due to resistive forces.
Q. Show that the load is undergoing simple harmonic motion.
Graph is a straight line, showing acceleration is directly proportional to displacement. Negative gradient of graph states that acceleration and displacement are in opposite directions.
