Forces 0.0 / 5 ? PhysicsForces and MotionIGCSEEdexcel Created by: DanielSmartCreated on: 07-04-15 15:18 Name the forces Weight, Friction, Air Resistance (or drag), Viscous Drag, Upthrust, Magnetic, Electrostatic, Normal Reaction, Tension. 1 of 11 What is the Unit of Force? Forces are measured in Newtons (N) 1N is roughly the weight of an apple due to the Earth's gravity. 2 of 11 Weight The force that acts on a body because of gravity 3 of 11 Friction The force that opposes motion, either when you try to make something move or while it's moving 4 of 11 Air Resistance (drag) Friction between an object and the air (or gas) that it is moving through 5 of 11 Viscous drag Similar to air resistance, but occurs when an object is moving through a liquid 6 of 11 Upthrust the upward force that liquids and gases exert on objects 7 of 11 Magnetic Forces that magnets exert on other magnets or things made of iron (or other ferrous materials) 8 of 11 Electrostatic The force between electrically charged objects 9 of 11 Normal Reaction The special name for the contact force that acts on an object pressing down on another object. 10 of 11 Tension In strings, cables, ropes, etc. that are being stretched (not slack) 11 of 11
