You will make quantitative measurements of the motion of a cart rolling down inclines of various small angles. Rather than measuring time, as Galileo did, you will use a Motion Encoder System to determine the acceleration.

Can these data be used in extrapolation to determine a useful value of g, the acceleration of free fall? We will see how valid this extrapolation can be. Galileo was able to measure acceleration only for small angles. The acceleration during free fall can then be determined from the graph. When sin(θ) is 1, the angle of the incline is 90°. A graph of acceleration versus sin(θ) can be extrapolated to a point where the value of sin(θ) is 1. The acceleration is directly proportional to the sine of the incline angle, θ. When the angle of the incline is increased, the acceleration also increases. Using time and position data, it is possible to calculate the acceleration of the cart. If the angle of an incline with the horizontal is small, a cart rolling down the incline moves slowly and can be easily timed. Then, you will use your data to extrapolate to the acceleration on a vertical “incline ” that is, the acceleration of a ball in free fall. In this experiment, you will see how the acceleration of a rolling ball or cart depends on the incline angle. Therefore, he decided to limit the acceleration by using fluids, inclined planes, and pendulums. Unfortunately, his timing devices were not precise enough to allow him to study free fall directly. One of his goals was to learn more about freely falling objects. During the early part of the seventeenth century, Galileo experimentally examined the concept of acceleration.
