(a) State Newton’s First Law of Motion.
(b) Distinguish between balanced and unbalanced forces. Give one everyday example of each.
(c) A stone lying on a smooth table is pushed simultaneously by two students. One student applies a horizontal force of 15N towards the right while the other applies 15N towards the left. Explain why the stone does not move.
(d) The student on the right now increases her push to 25N while the student on the left continues to push with 15N. In which direction will the stone begin to accelerate? Justify your answer in terms of the net external force acting on the stone.
