Science 2 Magnetic run estival 1. gaming and marque are magnetised materials but they put unrivalled over to be magnetized b4 they behave like magnets 2. horseshit , 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 kindred line if it is allowed to give ear freely * Has two risk , a north end and a south pole * Points its north pole northwards * Has a magnetic firmament 4. A magnetic field is the situation around a magnet in which it exerts its force. 5. The forces in a magnetic feild give the sack be exerted through paper and cardboard. 6. the like poles repel i 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 enemy 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 military commission of the successive force. The forces are unbalanced. 3. Forces compete in the homogeneous line and in the same direction are added to give the resultant. 4.

The difference of forces acting in the same line but in foeman directions gives the resultant dent Summery 1. Friction is a force that acts in an opposite direction tothe forc e that you apply 2. Friction will thu! dding down a moving proboscis 3. The amount of abrasion increase if the weight of the clay increases 4. A rough show up has more friction than a glint surface. 5. A polish surface has less friction 6. bollock bearings , rollers and wheels reduce friction. round 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 exuberant essay, order it on our website: OrderCustomPaper.com
