Subtopic: 3.1 Gravity, weight, and mass

Ac+vity: Linking weight and mass

Learning Objec+ve:- To inves)gate the rela)onship between mass and weight.

Materials required:- Force meter, clamp stand, mass hanger, and masses

Procedure:-

Set up the equipment as shown in the diagram.

1. Set up the clamp stand and a=ach the force meter securely and as low
as possible to prevent it from falling.
2. Ensure the force meter is set to zero before beginning.
3. Hang the 100 g mass hanger on the force meter and note the reading
(ensure the mass of the hanger is included).
4. Gradually add 100 g masses one at a time, each time recording the new
force (weight) shown on the force meter.
5. Record your results in a two-column table:
a. Column 1: Mass (g or kg) – Independent variable
b. Column 2: Weight (N) – Dependent variable
6. Plot a graph with mass on the X-axis and weight on the Y-axis.
7. Observe the graph and describe the trend or relationship shown.

Conclusion:- This concludes that weight is directly proportional to mass, that is, as the mass
increases, the weight also increases.

Questions:-

1. Why is it important to include the mass of the hanger when calcula)ng the total mass?
2. What does the slope of the graph between mass and weight represent?
