Quote from: TDoS on Aug 11, 2026, 10:26 AMYou only mentioned speed of the ball. How about its velocity? The ball isn't going up the hill linearly, it is spiraling around the hill, on a generally upward trajectory. Every time you look to the top of the hill, you can see it, right there! But then the ball travels laterally along a cone shaped hill, moving dozens of feet for every inch higher in elevation.
First of all, Speed and Velocity are synonymous, although V is a vector quantity with a direction. 2nd, absent any outside force besides Gravity, the ball travels straight up or down the hill, it doesn't spiral. Third. the velocity increases due to the force of gravity accelerating it down the hill.
Your understanding of Newtonian Mechanics is pathetic.
