TrueFalse The acceleration of an object is same in all inertial reference frames.
TrueFalse The work done by a constant force acting on an object is equal to the magnitude of the force times the distance the object moves.
TrueFalse The work required to lift a mass one meter depends on the speed at which it is raised..
TrueFalse A particle's kinetic energy can change without having any net work done it.
