Cambridge Secondary (7-9). Stage 8. MCE Science. Workbook - Unit 8: Forces and Motion - Question 21

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.



What do you think will happen if you place two identical weights at different distances from the fulcrum on opposite sides of the seesaw?
