This means less friction makes the car  go farthest. The sandpaper made the car go least farthest and  have the most amount of friction. This means the most amount of friction makes the car go least farthest. Our final conclusion is the smoother surface makes the car go farthest and the rougher surface makes the car go shortest.]]> 2018-01-25 14:55:17 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/224674418 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225808976 We learned that the wax paper made the car go farthest and have the least amount of friction. This means less friction makes the car go farthest and have the most amount of friction. The sandpaper made the car go the least farthest and have the most amount of friction. This means the most amount of friction makes the car go least farthest. Our final cocclusion is the smoother surface makes the car go farthest and the rougher surface makes the car go least farthest.  ]]> 2018-01-29 19:11:05 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225808976 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809094 We learned that the cardboard made the car go the fastest because it had the least amount of friction.  Wax paper had the second longest distance,and I knew that sandpaper would be last because of how rough it is. But wax paper did come pretty close to the cardboard. My prediction was correct about all  three of the materials. I knew that cardboard would be first because of how smooth it is. I knew that wax paper would be second because it wouldn't beat cardboard but I knew that it would beat sandpaper.]]> 2018-01-29 19:11:19 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809094 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809166 In my group, the car went the farthest on cardboard.  It went the  shortest on sand paper and middle on wax paper. I think I know why. The sandpaper has the most friction, so it stopped the car. The wax paper was kind of sticky, so it had the second most amount of friction. The cardboard has the least amount of friction and s a smooth surface, o the car went the farthest. So that's why the car went the farthest  on card board.]]> 2018-01-29 19:11:29 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809166 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809585 In my group the car went farthest on cardboard. I think is the case because it has the lowest amount of friction. Friction slows the car down so it doesn't go as far. That is why it went the shortest on sandpaper. It has a very rough surface so it has more friction then the smooth cardboard. So, the rougher the surface, the slower it goes, and the shorter it goes.

The car went the least farthest on the sandpaper because the sandpaper is bumpy and has the most amount of friction. That means that the car went the second farthest on the wax paper because the wax paper is made out of wax and when wax drys it gets a little bumpy, but not as bumpy as sandpaper. So we found out that the car went the farthest on cardboard.]]> 2018-01-29 19:12:20 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809598 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809631 My group learned that the car went farthest on cardboard because the cardboard has a smoother surface than the wax and sand paper. The  car went the least farthest on sand paper. It did this because it has the least amount of friction and it is very bumpy.That means that the car went second farthest on wax paper because the wax paper is made out of wax and when wax drys it gets a little bumpy , but not as bumpy as sand paper.

And when it went down the sand paper it went the slowest and got the shortest distance. Then with the wax paper it was the second slowest and the second farthest distance.]]> 2018-01-29 19:12:36 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809751 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225809840 We learned that the car went faster on cardboard.  This is true because  it has the lowest amount of friction. Friction would have made the car go slower, but it didn't.  Which is why it went the shortest distance on sandpaper.  The sandpaper´s rough surface makes more friction to slow the car down.

It made the car go the farthest because it had less friction on the car than the other material. I thought the wax paper would have the least amount of friction against the car because it's nice and smooth, but it turns out the cardboard had the least amount of friction against the car. I expected the sandpaper to have the most friction against the car, and it did I was not surprised at all. That is what I learned about that friction experiment, I hope you found that helpful.]]> 2018-01-29 19:13:06 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810010 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810288 My  group learned that the wax paper allowed the car to go the  farthest out of the 3 surfaces wax paper, sand paper, and cardboard. THe highest it went was 83cm. The cardboard was smooth.  Sand paper was not that bad. It didn't have that much friction so it went farther than the cardboard. The farthest it went was 59cm. The sand paper was not so smooth. The cardboard had the most friction out of all of them. So the car went the least farthest. The farthest it went was 45cm. It was surprising that the cardboard wasn't the farthest for the car even though it was the smoothest.]]> 2018-01-29 19:13:31 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810288 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810470 my group discover that the car went faster on cardboard, slower on sand paper, and in between on wax paper. The car went faster on because it has a smooth surface so it has less friction. The car went slower on sandpaper because it has a bumpy surface so it has more friction. The car went in the middle speed on wax paper because it has a rubbery, smooth texture so there isn´t too much or too less friction.]]> 2018-01-29 19:13:56 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810470 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810633 My group learned that the car went the farthest on cardboard.  The cardboard seemed to have less friction than the other two surfaces.  The car went about 122 cm. on the cardboard.  The  second surface with less friction is the sandpaper.  The car went 109 cm. on the sandpaper.  The surface with  the most friction is the wax paper. The car went about 101cm. on the wax paper. Since the cardboard had less friction the car traveled farther than the other two surfaces.]]> 2018-01-29 19:14:18 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810633 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810749 We learned that the wax paper made the car go farthest and had the least amount of friction.  This means less friction makes the car go farthest. The sandpaper made the car go least farthest and had the most amount of friction. This means the most amount of friction makes the car go least farthest. Our final conclusion is smoother surfaces have less friction and make the car go far.  Rough surfaces have more friction which makes the car go slow. ]]> 2018-01-29 19:14:32 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225810749 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225811597 My group learned that the wax paper allowed the car to go the farthest out of 3 surfaces. The 3 surfaces were sand paper, cardboard, and wax paper.  The cardboard had the most  friction  out of the 3 surfaces, so that cause the car to go the least farthest. The Cardboard also was a little bumpy, so that caused the car to slow down when it was going down the ramp. ]]> 2018-01-29 19:16:14 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225811597 ac094 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225812143 The Wax paper and sand paper have more friction, so the car's position is closer to the ramp.

Also, the wax paper surface was very smooth, and didn't have bumps on the surface. That allowed the car to go the fastest down the ramp out of the 3 surfaces. The farthest the car went was 86cm. The 3 surfaces were sand paper, wax paper, and cardboard. The cardboard had the most friction out of the 3 surfaces, so that caused the car to go the least farthest. The cardboard was also a little bumpy, so that caused the car to slow down when it was going down the ramp. The farthest the car went down the cardboard was 61cm. The sandpaper was in the middle of the 3 surfaces, so it didn't go the farthest, yet it went more than the cardboard. The sandpaper had some friction, when the car went down the ramp, the friction slowed the car down. The sandpaper had bumps on the surface, so that slowed the car down a lot. The farthest the car went was 59cm.]]> 2018-01-29 19:19:13 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225813332 https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225818362 2018-01-29 19:27:52 UTC https://padlet.com/perkiomenvalleyschooldistrict/pcbustxrzyb8/wish/225818362
