Frictional force and terminal velocity 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: nimrahali12Created on: 30-10-16 10:14 Friction is always there for? slowing things down 1 of 13 If an object has no force propelling it along it will always slow down and stop because? of friction 2 of 13 Friction always acts in? the opposite direction to movement 3 of 13 To travel at a steady speed , the driving force needs to? balance the frictional forces 4 of 13 You get friction between? two surfaces in contact or when an object passes through a fluid 5 of 13 Most of the resistive forces are caused by? air resistance or drag 6 of 13 The most important factor by far in reducing drag in fluids is ? keeping the shape of the object streamlined 7 of 13 The opposite extreme is? parachute which is about as high drag you can get 8 of 13 Drag increases as the ? speed increases 9 of 13 Frictional forces from fluids always increase with? speed 10 of 13 A car has much more friction to work when travelling at 70mph compared to? 30mph 11 of 13 So at 70mph the engine has to work much harder just to ? maintain steady speed 12 of 13 Objects falling through fluids reach? terminal velocity 13 of 13
