Additional physics: frictional force and drag 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: starshooter786Created on: 24-04-14 15:58 What is friction? Friction is a force that will always act in the opposite direction of movement. 1 of 7 When do you get friction? When two surfaces rub together, or when an object passes through a fluid. 2 of 7 What's needed to travel at a steady speed? The driving force needs to balance the frictional force. 3 of 7 What are most of e frictional forces caused by ? Drag or air resistance 4 of 7 What affects the drag of an object when it moves through a fluid? The shape of it. 5 of 7 What is the name for shapes that cause a small amount of drag? Aerodynamic 6 of 7 When do frictional forces from fluids increase? When the speed of the object increases. 7 of 7
