Aim of experiment: To find out the minimum amount of force (load) needed to overcome the inertia of the block.
(Inertia or reluctance of the object to change its position)

Materials: Block, load, table, string and pulley

Protocol:

1. Connect one end of the string to the block by tying it around the block.

2. Put the block on the table.

3. Put the pulley on the table.

4. Put the string through the pulley.

5. Connect the weights to the other end of the string.

6. Increase the number of weights in 10g succession until the block moves.

7. Count the weights needed for the block to move at the end of the experiment.

8. Repeat the experiment three times to ensure the results are reliable.

9. Find the average of the number of weights needed for the block to move.
