Science Experiment on Forces (Qin Ying, Amanda, Renesh and Rui Sian)

Aim:

To find out the minimum amount of force needed to overcome the inertia of the wooden block.

Protocol:

1. Place the ramp on the flat surface.

2. Place the wooden block just beside the ramp.

3. Hook the pulley to the block.

4. Add weights to the pulley till it is able to be pulled up the ramp by the force-meter. (Find out the least number of weights needed for each surface e.g. sandpaper, plastic sheet)

5. Take 3 readings per surface.

6. Fill in the table on page 13.

7. Draw a conclusion from the table (also on page 13).
