It is the force resisting the motion of masses of any kind. This force is caused by the roughness of the surfaces involved. This “roughness” is actually microscopic ridges, bumps, and hills, so to speak, appears on any surface regardless of how smooth it may appear. These irregularities lead to surfaces opposing each other. However, to put an object in motion, a force or an energy must cause it to move. In some cases, in order for an object to move, a third party energy or force must in some way interact with it. Take moving a desk for instance. No one ever sees desks moving on their own because they do not make energy to move. Therefore, they can only move if a third party energy or force interacts with it in a way. Moreover, this third party must overcome static friction.]]> 2018-03-01 19:30:30 UTC https://padlet.com/t_soroken/6tzjjbzfsyi5/wish/237139563 t_soroken https://padlet.com/t_soroken/6tzjjbzfsyi5/wish/237144651 Hypothesis: If I drag a mass over a flat cardboard surface, then a flat rubber surface, than the mass traversing over the rubber will require more force than going over the cardboard because the rubber creates more friction due to it having more surfaces for said mass to catch on.]]> 2018-03-01 19:37:51 UTC https://padlet.com/t_soroken/6tzjjbzfsyi5/wish/237144651 t_soroken https://padlet.com/t_soroken/6tzjjbzfsyi5/wish/237144948

The results came out that cardboard, on average, took around 175 N to pull, whereas rubber, on average, took 225 N to pull. This proves that things on rubber require more force to push/pull than on things such as cardboard, which means that my hypothesis was correct about rubber requiring more force than cardboard. However, errors or faults could have happened thus affecting the results of my testing. One potential one is that I might not have pulled things with an equal amount of force, while another being I might have pulled the objects across an uneven surface. Ultimately though, I have learned that there are a lot of factors that play into friction and that it is all around us, such as the movement of vehicles/organisms, avalanches, etc. And finally, another question we could ask based on my findings is if friction works the same way on different planets, no gravity, in the vacuum of space, etc.]]> 2018-05-21 18:34:29 UTC https://padlet.com/t_soroken/6tzjjbzfsyi5/wish/262470266 t_soroken https://padlet.com/t_soroken/6tzjjbzfsyi5/wish/264345715 1) Weigh object on gram scale.
2) Pull object across the first surface.
3) Record results.
4) Repeat steps 2 - 3 two more times.
5) Repeat steps 2 - 4 but with the second surface.]]> 2018-05-29 18:41:41 UTC https://padlet.com/t_soroken/6tzjjbzfsyi5/wish/264345715
