I I believe that the cone will roll up the rails as the cylinder will not because the cylinder is flat, and the centre of mass will not cause it to go upward. I think that the heavy cone will also roll up, but not all the way and much slower than the light cone.

The uphill roller is an object of round or cylindrical item by physical demonstration. The roller appeared to move uphill demonstrates centre of mass because of the positioning of the rolling object on the track the centre of mass of the rolling object is lower at the top of the track then the bottom, and so the object rolls uphill because the rail widen the overall height of the centre of mass decreases as the roller moves along the track, even as it appears to climb. An object always moves to minimize its potential energy which means lowering its centre of mass, so it’s always rolling downhill in terms of centre of gravity of.

Independent variable : the sheep/size of the roller (cone vs cylinder)

Dependent variable : how far uphill the roller goes

Controlled variable : angle of the rails

With my ramps at the same angle, I put the cylinder and the cone at the same spot on the ramp and gave them equal to roll up. I placed them and started a timer to see how long it would take the roller to go from point A to point B.

I saw that when I put the cylinder on the bottom of the ramp, it stayed in place and did not roll upward one bit. When I put the cone at the bottom of the ramp, it rolled up all the way to the top of the ramp the heavier cone also reached the top of the rails. But much slower.

The reason the cone rolled up hill and the cylinder did not is because the core concept is that the object moves to a position where its center of mass is lower. So since the cones center of mass is lowest at the top of the rails it rolls upward. The cylinders lowest center of mass is at the bottom of the rails so it stays in place.

In conclusion, I learned that if you change the shape of a roller, it will affect how it rolls. I also learned that changing the mass of the roller will in fact, change the speed at which it rolls and how far up the ramp it rolls.

The uphill roller applies to science by demonstrating that objects, specifically their center of mass, always move from higher to lower gravitational property. It proves that while the object appears to roll uphill, its center of mass is actually descending

1. My ramps were to steep 2. My heavy roller was too heavy 3. Rail were not perfectly parallel 4. Pushed the roller instead of letting them roll on there own

The main person that helped me is my science teacher Mrs.Pepper. She guided me through the steps of joining and working in science fair. I am so happy she was their to guided me and keep me on track. The other person I seeked help from is my friend who is also a grade 8 student. Aaliyah helped me think of this science fair topic and helped me figure out how I wanted to execute it
