1.The work required to lift a mass one meter depends on the speed at which it is raised..
2.The acceleration of an object is same in all inertial reference frames.
3.A particle's kinetic energy can change without having any net work done it.
4.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.Less power is required while lifting a box up quickly than while slowly lifting it.
6.A simple machine may reduce the force required to do a task
