A field, in physics, is a region of space where one object can affect another object without the two objects touching each other. The most familiar fields are gravitational and magnetic but now we need to gain some understanding of electric fields and their shapes. Let's start with a quick recap of what we know … Continue reading Electric fields
What is Static Electricity?
When work is done on an object, by moving a force through a distance, the object gains energy. As a result, the object might get hotter (gain thermal energy) or accelerate (gain kinetic energy) or be lifted upwards (gain gravitational energy). There is also another possibility; the object could gain electrical energy in the form … Continue reading What is Static Electricity?
Static Electricity: Uses and Dangers
It is important that you can describe and explain how static electricity is used, or avoided, in some real-life situations. A good way to recall example uses and dangers is to start from what they have in common; The uses all exploit electrostatic forces, which may either attract or repel objects.The dangers all involve sparks. … Continue reading Static Electricity: Uses and Dangers
