### Force and Newton Law

1. 1. FORCE This is HEAVY! I can’t hold it anymore! Can someone help me?
2. 2. FORCE • push or pull • object’s interaction with its environment • vector quantity • unit is Newton
3. 3. NET FORCE • the sum of all the forces acting on the object. • a physical quantity that is capable of changing an object’s state of motion 5 N3 N 3 N 5 N Net force = 2N, right Net force = 8N, right
4. 4. Four Fundamental Forces 1. Gravitational Force – Force of attraction between two masses Position of the stars and planets 2 21 r mm GFg
5. 5. 2. Electromagnetic Force Force that affects charge particles Your hair will be attracted to a charged balloon The electrons from the clouds will travel towards the land - thunderbolts
6. 6. 3. Weak Nuclear Force 4. Strong Nuclear Force Four Fundamental Forces Radioactive decay Binds proton in the nucleus
7. 7. Forces acted on an object 1. Weight - gravitational attraction of an object and the earth - always directed downwards - W = mg weight Normal force 2. Normal Force - support force exerted upon an object - perpendicular to surface
8. 8. Forces acted on an object 3. Applied force - force applied simply by pushing or pulling weight Normal force Applied force Friction 4. Friction - force exerted by a surface as an object moves across it - parallel to surface and opposite to the direction of motion
9. 9. Forces acted on an object 5. Tension - force which is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. T e n s i o n 6. Air resistance - force exerted by the air as an object moves in it - opposite to the direction of motion
10. 10. Newton’s Law of Motion 1. Law of inertia 2. Law of Acceleration 3. Law of Interaction
