# Electric Forces and theforce: Laws of Motion Section

Electric Forces and theforce: Laws of Motion Section 1 push or pull between 2 charged particles The attraction or repulsion between charged particles Forces and the Laws of Motion Section 1 Electric Charge:

physical property of an object that causes them to repel attract Basedoron protons (positively charged) and electrons (negatively charged) in an atom. Opposite charges (positive and negative charges) attract. Like charges (positive - positive or negative - negative) repel. Forces and the Laws of Motion Section 1

Electric fields exist around objects with a charge If a second object with charge is placed within the electric field, the two objects experience electric forces that can attract or repel them. Electric force decreases as distance between the objects increases. Forces and the Laws of Motion Section 1

Magnetic Force A push or pull that a magnet exerts on another object Opposite poles (north-south poles) attract each other. Like poles (north-north or south-south poles) repel each other. Forces and the Laws of Motion Section 1

Magnetic Force A magnet can exert force over a distance because the magnet is surrounded by a magnetic field. Forces and the Laws of Motion Section 1 Magnet- an object that attracts certain materials such as iron or other metals Have North and South magnetic poles.

Poles are regions where the magnet is strongest. Called poles because they line up with Earths North-South axis. Even if you cut a magnet, it will still have both North & South poles. Forces and the Laws of Motion Section 1 Magnetic fields exist around magnetic objects. If 2 magnetic objects are placed within the magnetic field,

the two objects experience magnetic forces that can attract or repel them. Magnetic force decreases as distance between the objects increases. Forces and the Laws of Motion Section 1 Magnetic Force The pattern of iron filings shows the lines of force that make up the magnetic field for this magnet.

The concentration of iron filings near the poles shows that these areas exert the strongest force. Forces and the Laws of Motion Electricity and magnetism areSection 1 related. Magnetic fields can produce electrical currents in conductors. Conductor - substance through which electrical charge can flow

Electrical currents can produce magnetic fields. Electromagnets - temporary magnets that lose their magnetism when the electric current is turned off
