Question

Select which of the following statements are True or False. Assume Newtonian Mechanics.
True False  The work required to lift a mass one meter depends on the speed at which it is raised..
True False  A particle's kinetic energy can change without having any net work done it.
True False  The acceleration of an object is same in all inertial reference frames.
True False  A simple machine cannot reduce the work required to do a task.
True False  Less power is required while slowly lifting a box than while lifting it up quickly.
True False  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.
