On practice exam 8 for AAMC:
When designing his experiment, Galileo (G) could have allowed spheres to drop from a height of 10m rather than using the 10m inclined plane. The main advantage of using the inclined plane is that on the inclined plane the:
(I eliminated the 2 very wrong answers)
A: Final velocity of the sphere is smaller
B: Spheres take longer to reach the bottom.
I chose B - which was right - however, couldn't you also say that A is true as well. It's a known fact, due to inertia, that the sphere rolls down slower than if it slid down.
