A block is placed on an inclined plane and remains stationary. A student claims, "The block remains stationary because as gravity tries to pull the block down down the ramp, the block exerts an equal and opposite force on itself up the ramp." Is the student's claim correct? Justify your answer.
- No. Newton's third law states the block cannot exert a force on itself.
- No. Newton's first law states the block's inertia must cause it to move down the ramp.
- Yes. Newton's third law states the block must exert a force equal and opposite to gravity.
- Yes. Newton's first law states the block must remain stationary unless pushed.
