Question

Galileo carried out his seminal free-fall experiment using and incline plane. Why is such and approach feasible,and sometimes preferable to the simple drop meathod, for determining g?

Answer 1

Since there is air resistance that affects the experimental value for g, it is hard to find that out. If there is an inclined plane that has very little friction, then all that is needed is the angle of the plane with respect to the ground, and the value would be accurate..

Answer 2

Thank you!
