Quiz Description

In this physics quiz, we shall be studying forces. Under forces, we will cover the definition of a force, the various types of forces, the effects of forces, and their analysis. This section is highly applicable in mechanics, hence, making this quiz very relevant to your physics studies. 

A force can be defined as a push or a pull exerted on a body or object. It is a vector quantity because it has a magnitude and it is always directed. A force can pull, push, cut, extend, compress or destroy an object. There are two main types of forces which are: Action-at-a-distance (non- contact) force and contact force. An action-at-a-distance force is that force that exists between two bodies that are not in touch or physical contact. Some examples are electrostatic, magnetic, and gravitational forces. On the other hand, a contact force is that force between two bodies that are in touch or physical contact. Examples are frictional force, normal reaction, upthrust force, etc 

As said earlier, if you are determined to be good at physics, then you need to practice more on topics like this. You need not to worry about that because this quiz has that covered. Good luck as you practice with us.
