1. For an object in circular motion, in what direction does the centripetal force act? (1 point)
a. in a line pointing forward of the moving object
b. toward the center of the circle**
c. in a line pointing behind the moving object
d. toward the outside of the circle
2. For an object spinning around a central point, what will happen if its distance from the center is decreased? (1 point)
a. Nothing will change.
b. Its acceleration will decrease.
c. The centripetal force will decrease.
d. Its acceleration will increase.**
3. In what way is an object moving in a circle always accelerating? (1 point)
a. Its momentum carries it forward.**
b. Its velocity toward the mass is always increasing.
c. Its velocity toward the center is always increasing.
d. Its velocity in a straight line is always increasing.
4. Why is it that if the centripetal force on an object increases, its acceleration increases? (1 point)
a. Its velocity increases.**
b. Its mass increases
c. Its velocity decreases.
d. Its mass decreases.
All my answers were right except for 3.
Correct answer: Its velocity toward the center is always increasing.
