Question: If  I change the mass of the block, how will the mass of the block affect the amount of force able to move the block?

Background Information: Friction is the resistance that one surface or object encounters when moving over another. A spring scale is a type of weighing scale. Motion is the action or process of moving or being moved. The surface is the outside part or uppermost layer of something. Sliding friction is resistance created by two objects sliding against each other. We can affect friction by pulling harder on the spring scale or pulling less on the spring scale. Friction relates to my investigation because the block that we are pulling is rubbing or sliding against the rubber causing friction. Mass affects friction by the force pushing or pulling the object on top.

Hypothesis: If I pull 3 different mass blocks, then it will be harder to pull because of friction. I think the result will be the lower massed block will be easy to pull and the normal block will be harder to pull and the most massed block will be the hardest to pull.]]> 2019-02-06 18:36:25 UTC https://padlet.com/c_hicks1/iu70deam2dux/wish/328423338 c_hicks1 https://padlet.com/c_hicks1/iu70deam2dux/wish/328424029 Materials:
Spring scale
friction boards
different mass blocks

Procedures:
1. Weigh the different blocks that you have.
2. Hook the spring scale on the hook on one of the different mass block.
3. Gently pull on the spring scale until the first block begins to move, repeat this two more times with the other blocks you have.
4. Record the highest force reading on the spring scale.
5. When you are done with the 3 trials record the average.]]> 2019-02-06 18:37:35 UTC https://padlet.com/c_hicks1/iu70deam2dux/wish/328424029 c_hicks1 https://padlet.com/c_hicks1/iu70deam2dux/wish/328424564 Observations and Data Collection: Control, original block: When we pulled the original block of 370g, it took on the first try 4N to pull it. On the second try, it took 5N to pull it and the same on the third trial. Variable, different mass blocks: When we tried to pull the 547g  block, it took 5N to pull it in all three trials. For the last trail we pulled a block of 48g, it took 0.5N for all three trials.

Presentation of Data: ]]> 2019-02-06 18:38:28 UTC https://padlet.com/c_hicks1/iu70deam2dux/wish/328424564 c_hicks1 https://padlet.com/c_hicks1/iu70deam2dux/wish/328424921 Analyze and Interpret Results: My results turned out this way because when we pulled the different massed blocks, the trials were different for all three blocks, also when I pulled the regular mass block (370g) the trials were the same. What I did in the experiment was to measure the force it took to pull different mass blocks. The numbers told me that the highest mass block took the most force to pull it, and the lowest mass block took the least amount of force to pull it. My hypothesis was correct because of 3 different massed blocks were harder to pull because of friction. An error or a fault that occurred was when we pulled the spring scale, the person that was pulling the spring scale stopped pulling to early and we couldn't record the force. That could affect my results because I could have a number that somebody said that's what they saw and it could be completely wrong. What I learned about science from doing my experiment is what sliding friction is and also how friction can be affected. This experiment applies to the real world because it can represent someone attaching a rope to something and pulling on grass, concrete, or dirt. Another measurable question that can be explored is, if I change the surface that I am pulling the block on it will affect the amount of force able to move the block.

Conclusion: The mass of block affects the amount of force able to move the block. I learned that it depends on the surface of the friction boards and the different massed block that you pull can cause different results. Also, my hypothesis was correct, if I pull 3 different mass blocks, then it will be harder to pull it on a rubber surface.]]> 2019-02-06 18:39:06 UTC https://padlet.com/c_hicks1/iu70deam2dux/wish/328424921
