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.
