1.

Which one of the following statement is an incorrect statement?

Answer»

work done by a force `W=F.dr cos theta`
kinetic energy = `(p^(2))/(2m)`
Potential energy of a body moving with constant VELOCITY is
`U=int F_(ext).dvecr`
POWER = Force `xx` Velocity

Solution :`K.E=(1)/(2)MV^(2)`
`=(1)/(2)((mv)^(2))/(m)=(p^(2))/(2m)`
