Hello There!

When an object moves in uniform circular motion, the direction of its acceleration is directed toward the center of its circular path.

Uniform circular motion is a certain object or thing that that is traveling in a circular path. The reason why "uniform" is there because a part of it has to stay constant.

C) is directed toward the center of its circular path.

Explanation:

Uniform Circular Motion happens when its trajectory is a circumference and its velocity modulus remains constant over time.

In our daily life we often observe the movement made by fans, car wheels and also by the blender. These are all examples of devices that use MCU.

Within the study of uniform circular motion there is the presence of centripetal acceleration, ie when there is speed variation there is acceleration.

Centripetal acceleration is always directed to the center of the circumference. It does not change the modulus of velocity and its mathematical representation is given by the equation:

acp = v2 / R or acp = ω2 R
