Question
An object moves in a circular path at a constant speed. Compare the direction of the object’s velocity and acceleration.
- Both are in the same direction
- Both are in opposite direction
- Both are perpendicular
- Incomplete information
Hint:
The velocity at any point in a uniform circular motion is given by tangent to that point in the direction of motion .
The correct answer is: Both are perpendicular
The velocity at any point in a uniform circular motion is given by tangent to that point in the direction of motion .
Now as it is a uniform motion it means speed is constant hence tangential acceleration is zero , ball has only centripetal acceleration , directed toward the center of circular path
So 90 degree is correct
