Physical Science Concepts to Study
... Mass is different from weight. Weight is determined by multiplying mass by the acceleration due to gravity at any location. Thus your mass stays the same while traveling to the moon but your weight would be less on the moon. Newton's third law speaks to forces that act together and is expressed by s ...

Static electricity
.jpg?width=300)
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.A static electric charge is created whenever two surfaces contact and separate, and at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shock–more specifically, an electrostatic discharge–is caused by the neutralization of charge.
