Question

Select which of the following statements are True or False. Assume Newtonian Mechanics.
TrueFalse A simple machine may reduce the force required to do a task.
TrueFalse The speed 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.
TrueFalse Less power is required while lifting a box up quickly than while slowly lifting it

**** These are the answers I have given. Please give all answers and feedback for why******
