THE PHYSICS OF THE ROLLER COASTER
Error justification - The error for height of release is based on the minimum scale on the tape measure 0.2cm. - The error for average radius is 0.4 cm because of the minimum scale of the tape measure is 0.2 and the method I used to measure the radius of the loop. I simply took the sum vertical and horizontal diameters of the loop and divided it by 2 to get the radius. Since there are 2 diameters, there is double the error of 0.2 cm.
