Web$\begingroup$ In regard to Chris2807's answer, I have a question: If a ball is rolling down the hill on its own, there is a continual component of gravitational force that pulls it down the incline. Since this force produces no torque about the center of mass, I have concluded that a frictional force must be exerted on the contact point at all times when the ball slides … Web1. dec 2014 · There is a ball rolling down an incline, with no slipping. If we consider the point of contact between the ball and the inclined plane to be the pivot point (for our torque calculations), then I have noticed that …

WebAnswer (1 of 9): No-body is perfect! As we cannot practically have a frictionless surface , similarly we cannot have a perfect sphere. So the very fact that the sphere is rolling … WebThat means when rolling the net force down the slope acting at the centre of mass must be smaller than when there is no rolling. Thus the frictional force must act the slope. The angular acceleration of the ball is in the clockwise … gif not an option in teams
