How is friction affected by Mass?
Group 6
Hypothesis
• Mass is directly proportional to Friction
Set-up & FactorSet-up• Wooden Block (160g) x5• Newton Balance x1• Rope
Factor• Independent Variables:• Mass
• Dependent Variables:• Friction
• Control Variables:• Pressure• Contact Surface Area• Humidity & Temperature
Experiment
1. Rope the wooden block with a rope2. Pull the first block with Newton Balance3. Add one more block on the top4. Repeat the action until the last block was
added to the top
5. Record the Max. Friction when the block moves in each test
