Compare the magnitudes of acceleration of two objects in each of the following scenarios. Provide evidence in the form of diagrams to justify your conclusions. 1. Two objects move with the same speed but move along curves that are different (e. g. a gentle turn vs. a tight turn taken at the same speed)

2. Two objects taking the same curve but at different speeds.

Find the direction of the acceleration for an object moving along an oval track and speeding up Provide evidence in the form of diagrams to justify your conclusions.

The centripetal acceleration of the car doing gentle curve is less than its counterpart of a sharp curve.

A sharp curve would have a lower curvature radius than a gentle curve:

Since the formula for the centripetal acceleration is

with r in the denominator.

if the velocity is the same, and the gentle curve has larger radius, then the centripetal acceleration of the car doing gentle curve must be less than its counterpart of a sharp curve.
