# Combined quiz on energy electricity forces and the solar system

#### Quiz Description

In this quiz, we will be looking at energy, electricity, forces and the solar system combined. Practically, you will be amazed to know that solar energy from the sun is used to charge up solar panels and these solar panels generate electricity as a product, which is electrical energy. This is a practical use of energy, and energy conversion makes this possible. On taking this quiz, you will learn things like forms of energy and energy conversion.

Energy is simply the ability or the capacity to do work. It exists in many different forms, electrical, heat or thermal, chemical, light, sound, and mechanical energy. Each of these energy forms can be converted from one to another as by the first law of energy.

Electricity is the flow of charge, and it is a secondary energy source. There are two types of electricity, Static electricity, and current electricity. Static has to do with charges at rest and current electricity studies charges in motion.

Now, let’s talk about forces, a force is that which can set an object in motion, change the direction of motion of an object, and can also stop an object from moving. A good example is an electrical force which is the pure attractive or repulsive force between two charged bodies.

The solar system is made up of our star, the Sun, and everything bound to it by gravity like our planet Earth and all the other planets.

These quizzes will help prepare you for your upcoming exams, be it SATs, GCE, or GCSE. More physics quizzes are also available. Take the quiz and see how ready you are for any upcoming test/exam.
Best of Luck!
