7. A Thought Experiment: Suppose that an object is moving in a clockwise circle (or at least trying to move in a circle).
- Suppose that at point A the object traveled in a straight line at constant speed towards B'. In what direction must a force be applied to force the object back towards B? Draw an arrow on the diagram in the direction of the required force.
1C
- Repeat the above procedure for an object moving from C to \( \mathrm{D}^{\prime} \). In what direction must a force be applied in order for the object to move back to point D along the path of the circle? Draw an arrow on
1C the diagram.
- If the acceleration of the body is towards the center, what is the direction of the unbalanced force? Using a complete sentence, describe the direction of the net
1C force that causes the body to travel in a circle at constant speed.
