Project Title:
Factors Affecting Friction
Problem Question:
To investigate how the weight of an object affects the amount of static friction between the object and the surface. Hypothesis:
The larger the weight of the object, the bigger the amount of static friction between
the object and the surface.

Apparatus and Materials Needed:
1. Tile
2. Electronic balance
3. Beaker
4. Water/Sand
5. Screw hook
6. Pulley system
Experimental Procedure Setup:
Step 1: Prepare a tile to use as the fixed surface
Step 2: Prepare 4 objects of the same material but of different weights
Step 3: Attach a hook to each object so that the pulley system can be hooked onto the object
Step 4: Weigh each object and record it down
Step 5: Place the object onto the tile and hook the pulley system to the object.
Step 6: Start adding weight to the load until the object moves
Step 7: Quickly catch hold of the load and take it out to measure how much it weighs.
Step 8: Record the weight of the load.
Step 9: Repeat step 4 to 9 for the rest of the objects
Independent Variable: Weight of the object
Dependent Variable: Amount of static friction between the object and the
surface
Controlled Variables (Constants):
Surface used throughout the experiment (tile), material of object, hook, pulley system.
