Falling objects and drag 5.0 / 5 based on 2 ratings ? PhysicsForces and MotionGCSEOCR Created by: Charlotte O'DwyerCreated on: 03-12-12 20:08 What happens when you drop an object? It falls directly towards the ground because of the gravitational attraction between the object and the object. 1 of 5 What happens when there is nothing to stop an object from falling? The gravity will cause it to start moving downwards the Earth. 2 of 5 However when an object is falling through the air.. there is a frictional force in the opposite direction called air resistance. As the speed increases, the size of the opposing drag force increases. 3 of 5 What happens to a falling object when there is no atmosphere? There is no drag force on a moving object. 4 of 5 How do you work out the weight of an object? mass of object x gravitational field strength 5 of 5
