Inclined Plane
Galileo used an inclined plane to determine the rate of acceleration due to Earth's gravity. In one experiment, he changed the pitch of the plane, but not its height.
What do you think he discovered?
the ball's speed at the end of the inclined plane is always the same
the ball's speed at the end of the inclined plane depends on the inclination
