    Question

    Which law determines the direction of an object’s acceleration as it is moving in uniform circular motion?

    1. Newton’s first law of motion
    2. Newton’s second law of motion
    3. Newton’s third law of motion
    4. Universal law of motion

    Hint:

    Because an object in uniform circular motion undergoes constant acceleration (by changing direction), we know from Newton's second law of motion that there must be a constant net external force acting on the object. Any force or combination of forces can cause a centripetal acceleration

    The correct answer is: Newton’s second law of motion

      Because an object in uniform circular motion undergoes constant acceleration (by changing direction), we know from Newton's second law of motion that there must be a constant net external force acting on the object. Any force or combination of forces can cause a centripetal acceleration
