Q782
The motion of a body around a circular path is an example of
A.
Uniform velocity, variable acceleration
AnswerB.
Uniform speed, uniform velocity
C.
Uniform speed, variable velocity
D.
Uniform speed, variable acceleration
Answer: Option A
Solution
Answer: Option A
Solution:
Uniform circular motion occurs when a body moves in a circular path with constant velocity. The acceleration of a body experiencing uniform circular motion is always directed toward the center of the circle (centripetal acceleration orac = V2 / r
where v is the body’s velocity, and r is the radius of the circle). This acceleration is constant in magnitude but changes in direction, so, it is variable at every point of the circular path.
