work is said to be done when a force produces displacement in a certain direction
P=W/t
W=FS
P=(50×5)/10
=250/10=25J
P=W/t
W=FS
P=(50×5)/10
=250/10=25J
kvnmurty:
units of power are J/sec or Watts.

Work is said to be done when a a force acting on an object displaces it from one point to another in it's direction.
Force (F)= 50N
displacement (s)= 5m
Work done = Fs = 50×5 = 250J
time elapsed = 10s
Power = W/t = 250/10 = 25 J/s = 25W
Force (F)= 50N
displacement (s)= 5m
Work done = Fs = 50×5 = 250J
time elapsed = 10s
Power = W/t = 250/10 = 25 J/s = 25W
