The velocity vector of the object at point G is the tangent along the path.
An object starts from rest at point F and speeds up continuously as it moves around an oval.
a. Choose a point about 1/8th of the way around the oval from point F, and label it point G. Draw a vector to represent the velocity of the object at point G
b. Determine the change in velocity vector between points F and G
c. How would you characterize the direction of Δv as point G moves closer and closer to point F?
d. Each of the following statements in incorrect. Discuss the flaws in the reasoning.
i. “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.”
ii. “The acceleration at point F is perpendicular to the curve”
