Practise explaining inward resultant force and acceleration in constant-speed circular motion, and predict how speed, radius and available force affect the path.
Fig. 2.2 shows a car travelling at constant speed around corner A on a road.
Fig. 2.2
On Fig. 2.2, mark with an arrow the direction of the resultant force acting on the car as it travels around corner A.
Corner B has a smaller radius than corner A . The car travels at the same speed around corner B as around corner A.
State how the resultant force changes due to the car travelling around a corner of smaller radius.
