WebThe tennis ball theorem can be generalized to any curve that is not contained in a closed hemisphere. A centrally symmetric curve on the sphere must have at least six inflection points. The theorem is analogous to the four-vertex theorem according to which any smooth closed plane curve has at least four points of extreme curvature. WebCycloidal is the shape of ramp that minimises the time of descent ... at least for a particle sliding frictionlessly down it - I think for a ball rolling, the optimum curve might well depart from cycloidality (I've often wondered that, but haven't searched into it.I would be glad to get comments about it, actually.). At the very top of the cycloidal ramp, the slope is actually …

Some people may … WebThe ball, if the string broke, would just follow Newton's first law. It says it would just travel in a straight line with constant velocity, and it would roll off the table. So the reason you have to pull on the rope to get the ball to go in a circle is not because there's an outward force but because this ball wants to maintain its velocity.
WebThe radius of curvature (R) of the flight path depends on the velocity (V) of the pitch and the acceleration (a) produced by the force. R = V ^2 / a We can solve for this acceleration from Newton's second law of motion using the force for a spinning ball and the mass (m) of the baseball (5 oz.).
