Procedures | 
1. Measure the mass of your wooden block using the triple beam balance
2. Measure the length, width, and height of the block, so that you know which block you used.
3. Record the length, width, and the height of the block so you can identify which block you used.
4. Hook up the spring scale to the hook on the block and pull the block until the block moves. Record the force used to pull that block
5. Repeat each step to step 4 but this time change the size and mass of the block.
6. Repeat the experiment to find the average of the amount of force needed to pull each block as a average of 3 trials.
7. Observe and conclude your data.

Variables: The different sizes and masses of the blocks

Constants: The material of the block, the friction board, and rate of drag.]]> 2019-02-06 18:39:53 UTC https://padlet.com/r_johnson4/g4ij9m5ku2g9/wish/328425517 r_johnson4 https://padlet.com/r_johnson4/g4ij9m5ku2g9/wish/328427209 Observations and Data Collection | 
Presentation of Data | The block with a mass of 547 grams has the highest average of force needed to pull the block along the friction board. The gram with the second most amount of force needed to pull the block was the block with a mass of 370 grams. Each trial was 4.25 N, 4.5 N, 4.1 N. It too a average of 4.2 newtons.

For example, the block with a mass of 547 grams had the highest average of force needed to pull the block along the friction board. I think this is because there is a larger gravitational pull towards the friction board through the larger blocks. Therefore acting a force on the block will also have to push against gravity.
Conclusion | My hypothesis was correct and the more mass a object has will affect the amount of friction affected on that object. A alternative question of a different inquiry I would have would be: Does different thickness of the friction board change the amount of friction acted upon the object?]]> 2019-02-06 18:43:08 UTC https://padlet.com/r_johnson4/g4ij9m5ku2g9/wish/328427700 r_johnson4 https://padlet.com/r_johnson4/g4ij9m5ku2g9/wish/346984284 Question | Friction against a Block
Background Information | How does friction affect the amount of force needed to move a object?
According to Newton's 2nd law of motion, the higher the mass of a object the more force needed to move the object. Friction is a force that opposes a object moving against a other, this results in the need of more force to move a object with friction. Objects with higher mass and more friction will require more force to drag than with lower mass and lower amounts of friction.
Hypothesis: If the mass of a wooden block increases then the amount of friction acted upon that block will increase because the objects with larger masses need more force to move.]]> 2019-04-01 01:00:40 UTC https://padlet.com/r_johnson4/g4ij9m5ku2g9/wish/346984284
