An object moves with uniform speed round a circle. Its acceleration has
A
constant magnitude and constant direction
B
constant magnitude and varying direction
C
varying magnitude but constant direction
D
varying magnitude and varying direction
Verified Correct Answer: B.
Physical Principles & Numerical Solution
When an object moves with uniform speed in a circular path, its acceleration (centripetal acceleration) has a constant magnitude but changes direction continuously as the object moves around the circle. This acceleration is always directed towards the center of the circle.
