Question

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

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

b. 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.

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

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

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

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

a) false, it depends on force and distance.

b) true

c) false

d) true, particle in circle with changing velocity

e) false, power = work/time so time less power more

f) false
