         <description><![CDATA[<div>Question</div><div>By testing an object against a friction board mostly by mass will the mass of the object affect the total friction of the friction board, will different masses of objects increase or decrease the force of friction between two objects, and finally will I be able to test the force of the friction?<br><br></div><div>background information<br>Friction is the force of resistance to the relative motion of two objects or materials and friction is heavily relied on by most land vehicles, the roughness of the surface may impact the total friction of the objects or materials.friction between two surfaces converts  Kinetic energy to thermal energy. There are two main types of friction one is kinetic friction and the other is static friction.Static friction engages between two surfaces that aren't moving relative to each other, while kinetic friction results in two objects going in an opposite direction as its movement. In nature there is no frictionless environments neither in space or an atom. Mass also has a huge impact on the friction of objects by the force the force that's pushing them together which relates to the objects mass. The higher the mass the higher the reaction because of the kinetic friction that increases as the mass gets higher<br><br>hypothesis<br>If I increase the mass in the object then it will affect the normal reaction which will interned, increase the frictional force to the friction board.</div>]]></description>

         <description><![CDATA[<div>Observations and data collection<br>My observations when i was doing this experiment is that the three blocks where a different mass which effected the total friction between the blocks. The heavier one was as i predicted in my hypothesis had more friction because of the mass of the object. The data that i collected in these three trials of the blue heavy block is that in the first trial it was 3.5 newtons the second trial was quite interesting because it was the lowest one and was at 1.5 Newtons the third and final trial was at 3.5 Newtons which the average was at 2.8 Newtons for the blue block as i observed in these trials of this block i saw that it took more force to push the block when we were trying to pull the block with the spring scale.For the second block it was the second heaviest and was a red block we used the same friction surface which was our control but our variable was the different types of blocks. but for the trails for the red block were 1.4 newtons for the first trial 1.3 newtons for the second trail and finally 1 newton for the final trial  which the average newtons for this trial is 1.3. For the final block the lightest one it was .5 newtons for the first trail, .4 newtons for the second trail, and .5 newtons for the last trail and the average for this tan block was .5 newtons. As i observed the blocks moving i saw that the heavier one tended to stop more while the lightest block was easing through the friction board.<br>Presentation of Data<br>https://docs.google.com/spreadsheets/d/1EYFtTl79Lo2d7mGxVdNVk9FPgG1Ub7ssF9ipQ0-IUG4/edit?usp=sharing</div>]]></description>

         <title>Analyzing and Interpreting Results</title>

         <description><![CDATA[<div>Analyze and Interpret Results<br>We measured the block and weighed the block so we could know the differences between them and they all mostly had different lengths,widths, and heights but the masses were much different between them. Also we used a spring scale to drag and measure how much newtons each block had we did this for 3 trails for all 3 blocks. As we saw from our results it seems that the variable, mass of the objects do have something to do with the friction between them. we tested multiple times and the results were mostly the same. the second trial for block 1 got us by surprise because it was so low. My hypothesis was right the mass of the object would effect the total newtons the outcome would have. Mass had a huge impact on the test we had did. the mass of the object had a huge impact on friction. it would get harder and harder to pull the objects as the mass increased. Thats why the newtons had changed because mass increases the the normal reaction of the kinetic friction.<br>Conclusions<br>We had multiple errors for example we were dragging the blocks around with the spring scale wrongly and we had to fix that a lot of times. Sometimes the block would stop and then get stuck on the friction board but eventually we figured how to do it right. I've learned that friction has a lot to do with our world and the ground could affect our vehicles and many things in the place we live. We also could use friction as an advantage like the griptape on a skateboard helps you not slip and fall off it and also car tires different type of tires help you in different situations.Other questions that i had were does the affect of other type of friction boards have different forces in kinetic energy? or does different type of blocks have a different type of scratch on a friction board?</div>]]></description>
