Addition and Subtraction of Vectors

The combining of vectors is not as simple as the process of adding scalars. Vectors have both magnitude and direction, and simply combining two vectors doesn’t result in their total. For clarity, consider an example of a car traveling 10 miles North and 10 miles South. Although the car has covered a distance of 20 miles, the net displacement is 0. Both North and South travel are vector quantities, and their opposite directions cancel each other out. In this piece, we will delve into the methods for combining and separating vectors.

Electric Charge & Static Electricity | Definition & Examples

Have you felt the sudden painful jolt you get when you brush someone’s arm? If you have a woollen blanket then you should definitely do this, switch off the light and brush your clothes with the woollen blanket. The amount of sparks that go off will amaze you. Believe it or not, this very phenomenon is also responsible for all the lightning strikes on our planet. So what is it? It is known as Static Electricity. Static electricity can be a nuisance or even a danger. The energy that makes your hair to stand on end can also damage electronic equipments and cause explosions. To understand static electricity, we need to first understand the basics of atoms and electric charge.
