Question

Select which of the following statements are True or False. Assume Newtonian Mechanics.

Less power is required while lifting a box up quickly than while slowly lifting it.

A simple machine cannot reduce the work required to do a task.

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.

A particle's kinetic energy can change without having any net work done it.

The work required to lift a mass one meter depends on the speed at which it is raised..

The speed of an object is same in all inertial reference frames.
