Newton's first law says it will move at a constant velocity unless a net force acts on it. An object in uniform circular motion has a changing velocity, therefore it has a net force.

b) False

Final answer:

An object in uniform circular motion has a changing velocity, therefore it has a net force.

Therefore, the statement is True.

Step-by-step explanation:

The question is asking whether it is true or false that an object in uniform circular motion has a changing velocity, therefore it has a net force. According to Newton's first law of motion, also known as the law of inertia, a body at rest remains at rest or, if moving, remains in motion at a constant velocity unless acted on by a net external force.

In the case of an object in uniform circular motion, there is indeed a net force acting on it that is constantly changing its direction. This force is called centripetal force and it is responsible for keeping the object moving in a circle. Therefore, the statement is true and the answer is a) True.
