Question 28
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.
In Step 6, identical weights began at equal distances on opposite sides of the balanced seesaw; one weight was moved nearer the fulcrum. Based on your knowledge of moments, explain your observations in Step 6.
