Question 25
Think like a scientist: Measuring balanced and unbalanced forces. You will investigate the effects of balanced and unbalanced forces. Work in pairs. You will need: two forcemeters, piece of string, coloured tape, scissors. Set up the equipment as shown in the diagram. Each person in the pair holds one forcemeter (also known as a newton meter). The string should be tight. The coloured tape on the string should be lined up with the coloured tape on the desk. Each person pulls with an equal force, for example, 4 N.
This investigation is an analogy of a tug of war. That means the investigation can be compared with a tug of war. State what is represented by the forcemeters in this analogy.
