positive and negative charge‚ electric field line and explain how mass affects the motion of the “puck.” This simulation project is all about getting the puck into the goal while surround the puck with using few positive and electric charges. The positive charges have made the puck bounce back off‚ while the negative charges have made the puck oscillate to each there meaning that the puck and negative charges are compatible and moves towards each other. However‚ the two charges and the electric field

Because they are such unique organisms‚ they accumulate different metal anions in the air than other organisms‚ like plants do‚ for example. Lichens attract toxic metal ions. An ion is a charged atom. If the ion has a positive charge‚ it is a cation. An ion with a negative charge is an anion. During the ion exchange process‚ Hydrogen‚ an anion‚ is released and metal cations move in. This process occurs when lichens are exposed to polluted air. When the lichens are dropped into any of the metal solutions

called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton‚ and the number of electrons in an atom is usually equal to the number of protons. When the balancing force between protons and electrons is upset by an outside force‚ an atom may gain or lose an electron. When electrons

EQUIPOTENTIAL SURFACES COMPUTER LAB ACTIVITY Name:__ ________________________ Remember that an equipotential surface is the set of all points around a group of charges that are at the same potential. Hese surfaces allow us to calculate the amount of work needed to move a charge from one spot to another. The amount of work needed to move a charge q through a potential difference ΔV is given by: W=qΔV The purpose of today’s activity is to make you familiar with the shape and appearance of these equipotential

you can prove that electric charges can produce by using only a balloon and pieces of papers you can understand further static electricity and charges. And how it is produced. Introduction Have you ever wondered why rubbing a balloon make pieces of paper attract with it? The effect is due to static electricity‚ but how is the static electricity made‚ and why does it make pieces of papers attract in the balloon? Static electricity is the buildup of electrical charge in an object. Sometimes static

neutrons. Protons have a positive charge (+)‚ electrons have a negative charge (-) and neutrons have no charge at all‚ they are neutral. Atoms normally have the same amount of electrons and protons‚ making them neutral and having no charge. When rubbing things together‚ electrons can move from one atom to another‚ resulting in some atoms having extra electrons and a negative charge. The other atoms now have more protons than electrons and a positive charge. When the charges are separated‚ it is static
