2 True False The acceleration of an object is same in all inertial reference frames.
3 True False A simple machine cannot reduce the work required to do a task.
4 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.
5 True False Less power is required while slowly lifting a box than while lifting it up quickly.
