2 devices that use static electricity to funtion 1. Van de Graaff generator When the motor is turned on‚ the lower roller (charger) begins turning the belt. The belt is made of rubber and the lower roller is covered in silicon tape‚ the lower roller begins to build a negative charge and the belt builds a positive charge. Silicon is more negative than rubber so the lower roller is receiving electrons from the belt when it goes over the roller. The positively charged atomic nuclei‚ try to

Static Friction INTRODUCTION When an object is placed on a surface it will remain static unless the resolved component of the force due to gravity acting parallel to the surface exceeds the friction force associated with the static coefficient of friction between surfaces by placing various objects on a surface and tilting the surface until the object begins to slip. By measuring the angle at which the object begins to slip‚ it is then possible to calculate the coefficient of friction between

Definition Of Static Electricity Static electricity is the buildup of electrical charges on the surface of some object or material. Static electricity is usually created when materials are pulled apart or rubbed together‚ causing positive (+) charges to collect on one material and negative (−) charges on the other surface. Results from static electricity may be sparks‚ shocks or materials clinging together. Static electricity is the accumulation of electrical charges on the surface

Electrostatic Field • An electrostatic field is a phenomenon that is very similar to a magnetic field. When an object is electrically charged‚ it creates an electrostatic field. If an object has an excess of electrons‚ then it’s considered to have a negative charge. If an object has fewer electrons than its surrounding environment‚ though‚ it’s considered to be positively charged. Just like with magnetic fields‚ two objects that are oppositely charged will attract each other. This scientific

about us and how we identify ourselves‚ throughout the experiences we face in our lives. Identity formation is defined as the combination of personal‚ social and cultural experiences that combine to form an individual’s identity. Identity is not static‚ and never will be; it is the result of continuous interaction with the environment. People in our lives such as friends‚ family‚ teachers and idols affect the way we identify ourselves; they are a big factor in building our personality. Past experiences
