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 don't 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 don't understand why 1 is incorrect. it seems right to me..
