Question
For each of the following statements, determine whether it is trueor false.
The work done to raise a box onto a platform depends on how fast itis raised.
Work can be done in the absence of motion.
The kinetic energy depends on the reference frame of theobserver.
The gravitational force is a conservative force.
If the earth revolves around the sun in a perfectly circular orbit,then the sun does do work on the earth.
The kinetic energy of an object depends on the direction of themotion involved.
Spring B is stiffer than A (kA < kB). Morework must be expended on spring A if both springs are stretched bythe same amount.
The kinetic energy can be negative.
