A car is on a circular oval-shaped track and at point F, the car is at rest. about 1/8th of the way around the oval from point F, there's a point G. Now i dont understand why the following two statements are incorrect. 1. The acceleration at point F is zero. As point G becomes closer and closer to point F, the change in velocity vector becomes smaller and smaller, eventually it becomes zero. 2. The acceleration at point F is perpendicular to the curve. 2 is incorrect because acceleration at point F is zero since the car is at rest. but i dont understand why 1 is incorrect. it seems right to me..
