Question

Define power. obtain an expression for it in terms of force and velocity

Answer 1

____________****_____________
HERE IS UR ANSWER
POWER: the rate of doing work is called power
FORMULA: P=W/t ---------------1
we know that work =force ×displacement
W=F.S
W=F.S put this in equation 1
P=F.S/t -----------2
we know that :
velocity is the rate of change of displacement ,i.e v=s/t ,so put this in equation 2
P=F.v
