Occurs when objects contact with each other 2 of 29 What is non contact force? Occurs when objects do not contact each other 3 of 29 Is normal force contact or no contact force? Contact force 4 of 29 Gravity? Non contact force 5 of 29 Friction? Contact force 6 of 29 Magnetic force? Non contact force 7 of 29 Upthrust? Non contact force 8 of 29 Surface tension? Non contact force 9 of 29 Air resistance ? Contact force 10 of 29 Tension course ? Non contact force 11 of 29 What is deformation? When the force is removed the object changes shape for a period of time 12 of 29 What is elastic deformation? When the force is removed the object goes back to its original shape 13 of 29 What is plastic deformation? When the force is removed the object CANNOT return to its original shape 14 of 29 What is used to measure forces? A Newton meter 15 of 29 What 5 things can forces make objects do? Speed up, slow down, change direction, turn, change shape 16 of 29 How can you show the direction of a force? With an arrow, the longer the arrow the greater the size of the force 17 of 29 What is a balanced force? When a force on an object has the same size in the forward and backward force 18 of 29 What will the object do if it has a balanced force? The object will stay stationary or move in the same direction at the same speed 19 of 29 If the forwards force is greater than the backwards force what will the object do? Speed up 20 of 29 If the backwards force is great her than the forwards force what will the object do? Slow down 21 of 29 What is a resultant force? The resultant force is a sum of all forces acting on an object 22 of 29 What is friction? Friction is a force that acts on 2 surfaces when they move against each other. 23 of 29 What 2 things can friction do to an object? Friction can either stop an object from moving or slow it down 24 of 29 When does friction occur? Friction occurs when surfaces are bumpy even if that cannot be seen by your eyes 25 of 29 How can friction be reduced? By oil 26 of 29 How can friction be increased? By carpet or sandpaper 27 of 29 When is friction usefull? To keep your hands warm 28 of 29 When is friction not usefull? When you want to move an object across a rough surface 29 of 29
