Might be described as "lack of centripetal force. " 1. Defined by Isaac Newton in 1684, "The force that keeps an object moving with uniform speed along a circular path" 2. Formula, : F = mac = mv²/r 2. Formula, : F = mac = mv²/r 3. The direction is along the radius of the circle, from the center towards the object. 3. The direction is along the radius of the circle, from the object towards the center. 4. Centrifugal force is not a real force, it is inertia of motion (moving) 4. Centripetal force is a real force; it keeps the object from flying out. 5. Example: Mud flying off the wheel tire. Example: Satellite orbiting a planet Questions: What is a force? Differentiate between Centripetal force and Centrifugal Force? Define Newton's second law and third law of motion?
