Question
All of these are properties of an object moving in uniform circular motion except
the centripetal force acting on the object points toward the center of the circle
the speed of the object is constant
centripetal acceleration measures the change in speed of the object
the direction of the velocity of the object constantly changes direction
all of these
a.the centripetal force acting on the object points toward the center of the circle
b.the speed of the object is constant
c.centripetal acceleration measures the change in speed of the object
d.the direction of the velocity of the object constantly changes direction
e.all of these
Explanation / Answer
The correct option is (c). Because, the centripetal acceleration acts toward the center of circle. It does not measure the speed of the object in it path. The tangential acceleration measures the the change in speed of the object.
