frictional force
In physics work is dome when a force acts on a body and the body moves in the direction of the force.
WORK = FORCE x DISPLACEMENT
According to Newton's first law of motion, as a force acts on a body then the body gets accelerated in the direction of the force.
Centripetal force refers to the force that acts on a body moving in a circular path. It does not do work on an object because it acts perpendicular to the motion of the body. The work done on a rotating object is zero.
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Work W. The dot product of Force and Distance through which the force acts is called Work . W=F.d
Reaction pairs work on the same things and in opposite directions.
