Goal: The experimental goal of the lab is to measure the acceleration of the marble as it moves down an incline of angle and to compare the experimental value to the theoretical frictionless acceleration of a = g sin(theta).

theta=13 degree and uncertainty =0.6

Find a and a

a = g*sin(theta)

One way to do it is with derivatives:

da/d(theta) = g *cos(theta)

da = g* cos(theta) * d(theta)

a = g cos(theta) (theta)
