Option (a) is correct. The motion of a ball moving in a circular path at a constant speed is termed as the motion with acceleration.
Explanation:
The acceleration of a body is defined as the rate of change of velocity of the body. If the velocity of object under motion continues to change during the motion, the object is considered to be moving under acceleration.
The change in velocity is not only about the change in the magnitude of the speed of the object but it is also the change in the direction of motion of the object moving at a constant speed.
The motion of a particle in a circular path at a steady speed is an accelerated motion because the direction of motion of the ball changes at every instant during its motion in a circular path. The change in direction also changes the velocity of the object and therefore, it is categorized as the accelerated motion.
The motion of a particle at constant velocity in vacuum, a skater moving with a constant speed on a straight track and a vehicle moving on a street at steady speed are not considered as the accelerated motion because the velocity of the body does not change and the direction of motion also remains the same during the motion.
Thus, Option (a) is correct. The motion of a ball moving in a circular path at a constant speed is termed as the motion with acceleration.
