Question 23
In this investigation, place a sturdy plank (1–2 metres long) on a fulcrum so it is evenly balanced. Mark evenly spaced points on each side using a metre stick or tape measure. Use weights of known weight. Work in groups.
Place identical weights at the same distance from the fulcrum on each side of the seesaw. Make sure that the seesaw is evenly balanced. Predict what will happen if you move one weight closer to the fulcrum.
