WORK(W)
WORK(W)
The work done by a constant
force acting in the same
direction as the
displacement.
W = Fs (N-m or Joules)
The work done by a constant
force acting at an angle to the
displacement.
W = Fscos

MECHANICAL WAVE
Wave occurs whenever a system is disturbed from equilibrium
due to transfer of energy and when the disturbance can travel
or propagate from one region of the system to another.
