Define oscillations
backward and forward motion between two limits
Define free oscillations
No energy loss or gain
Define simple harmonic motion.
occurs when acceleration is proportional to displacement from a fixed point and in the opposite direction
Define damping
the loss of energy from an oscillating system
when there is a resistive force acting on the system
Define resonance
involves a maximum amplitude of oscillations and that this occurs when an
oscillating system is forced to oscillate at its natural frequency
State what is meant by centripetal acceleration
acceleration perpendicular to velocity
