E. Stays unchanged 12. An object travels in a circular path of radius r at a constant speed v. What happens to the object’s acceleration if the speed is doubled and the radius stays unchanged? A. It doubles B. It quadruples C. It is cut to a half D. It is cut to a quarter E. Stays unchange

e. As the radius of the circle is doubled, the acceleration is __________________ (one-fourth, one-half, two times, four times) the original value.

n object of mass m moves at a constant speed v around a circular path of radius r. The net force applied on the object is F. What happens to the net force if speed is doubled and radius is quadrupled? A. It doubles B. It quadruples C. Stays the same D. It is cut to one-half E. It is cut to one-quarter

How does the radius of an object moving in a circular path relate to its acceleration?  If the radius  increases, what happens to the acceleration?

c. As the speed of an object is doubled, the acceleration is __________________ (one-fourth, one-half, two times, four times) the original value.

An object moves in a circular path at a constant speed. Which of the following is true? A. The car’s acceleration is zero because it has a constant speed B. The car’s acceleration is not zero and causes the car to slow down C. The car’s acceleration is not zero and causes the car to speed up D. The car’s acceleration is not zero and causes the change in the direction of the car’s velocity E. None from the above
