|
|
|
The speed of the object varies.
|
|
|
The net force on the object is directed toward the center of the circular path.
|
|
|
The direction of the object’s velocity is constant.
|
|
|
The net force on the object is directed away from the center of the circular path.
|
Detailed explanation-1: -Reason: In uniform circular motion the magnitude of acceleration remains constant but the direction continuously changes.
Detailed explanation-2: -For objects in uniform circular motion, the net force and subsequent acceleration is directed inwards. It is often said that circular motion requires an inward (or “centripetal") force. Without a centripetal force, an object in motion continues along a straightline path.
Detailed explanation-3: -In the case of an object moving in a circular path the acceleration is directed toward the center of the circle. Therefore the net force is also directed toward the center. This net force is often called the centripetal force.
Detailed explanation-4: -To summarize, an object in uniform circular motion experiences an inward net force. This inward force is sometimes referred to as a centripetal force, where centripetal describes its direction. Without this centripetal force, an object could never alter its direction.
