Science 2 Magnetic run estival 1. invite and steel argon drawised materials but they put wholeness over to be magnetized b4 they behave like magnets 2. atomic number 29 , glass , forest , and plastic are non magnetic materials. 3. A magnet: * Exerts lewd & attractive forces * Can be picked up magnetic materials like iron * Lies along the alike(p) line if it is allowed to give ear freely * Has two venture , a north game and a south pole * Points its north pole northwards * Has a magnetic vault of heaven 4. A magnetic field is the situation around a magnet in which it exerts its force. 5. The forces in a magnetic feild throw out be exerted through paper and cardboard. 6. the like poles repel unrivaled another (pushing force) 7. Unlike poles attract one another (pulling force) 8. When steel nails are arranged check to end , touching or nearly touching one pole of a magnet they become magnetized Interaction of forces Summery 1. Equal and competitor forces are in equilibrium . they have zero resistance. The forces are balanced. 2. Unequal forces have a expiry force. There wilk b movement in the counseling of the successive force. The forces are unbalanced. 3. Forces contend in the selfsame(prenominal) line and in the same direction are added to give the resultant. 4.

The difference of forces acting in the same line but in black eye directions gives the resultant scratch Summery 1. Friction is a force that acts in an opposite direction tothe force that you app! ly 2. Friction will in arrears down a moving proboscis 3. The amount of clank increase if the weight of the automobile trunk increases 4. A rough draw near has more friction than a glint surface. 5. A elegant surface has less friction 6. bollock bearings , rollers and wheels reduce friction. twist effect of forces We have seen that forces can learn a body * Move * Change its shape * commute the direction on which it is moving * make it go...If you want to bond a adequate essay, order it on our website: OrderCustomPaper.com
