The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:
Physics permeates our day to day life. It also originates from various forces occurring in the universe. Macroscopic and microscopic details of the universe also form a significant part of physics. There are four basic fundamental forces in physics among which gravitational force is a major force.
Some of the forces which are a part of our day to day life are – muscular, friction, compression, elongation, gas pressure, electric, magnetic, and likewise. All of the above-mentioned forces are derived forces, which have originated from the fundamental forces given below. Let’s have a look at some of the important fundamental forces:
Have a look at the below-mentioned table to know some of the basic difference between these forces –

This is a hypothesis that is based on the law of observation and experiment. If required then this can be verified with the help of experiments.
The physical world is a very wide subject and it’s quite important to understand it fully. Other than the above-mentioned laws and forces, there are a number of other auxiliary forces that govern how the physical world moves. For having a detailed read and complete understanding of the concept, have a look at the MSVgo application. All the concepts and related topics are explained in simple language through videos and examples. For example, you will find multiple videos on gravitational forces where the entire topic is well explained with the help of examples.
1. What is the physical world?
The physical world refers to the laws of nature, forces and its applications around us.
2. What is the study of the physical world around us?
By study of the physical world, we mean the study of the non-organic world.
3. What is an example of physical science?
Any study related to inorganic beings is termed as physical science. For example, a study related to the moon, the earth, the sun can be termed as physical science.
4. What are the 5 major divisions of physical science?
Physical Science has 5 major divisions which are given below:
