Document Summary
The ferris wheel is at a constant speed and the center of the ferris wheel is to the right of the left most position, so the acceleration is pointing towards the center as defined in centripetal acceleration. A body in uniform motion remains in . Uniform motion , and a body at rest, unless it is triggered by an external force; a nonzero net force. It is force that is only required to change an object"s motion. It does not take a force to maintain an object"s motion. An object at rest or have a constant motion. The vector sum of all forces that acts individually on the object; the total of all vector forces that are added together. This includes contact and non-contact forces on the object. The rate at which a body"s momentum change is equal to the net force acting on the body. It is the product of the object"s mass and its acceleration.
