The chapter will introduce you to the concepts of force. Previously, you have learned the different kinds of forces simply. This time, you will learn how force is defined and classified into different types. The introductory section will also describe how this physical quantity is measured and the unit is determined.

All the intext and exercise NCERT Solutions for Class 8 questions have been solved in a detailed and step-by-step manner so that students do not face any difficulty in understanding them. Here you will learn what force and pressure are. You will learn the various characteristics of force like force can change the state of motion of an object and its shape, and that it has both magnitude and direction. You will also learn about contact forces muscular force, friction, etc. Lastly, you will learn about pressure — the pressure exerted by liquids and gases and atmospheric pressure.
CBSE Class 8 Science Revision Notes Chapter 11 - Force and Pressure
Examples: To kick ball we need to push it, to pick the book we need to pull it, and to lift the box we need to push it. When two or more forces are applied in the same direction, then the net force is the addition of magnitude of both the forces. When two forces are applied on an object in the opposite direction-. When two or more forces are applied over an object in the opposite directions, the net force is the difference of magnitude of two forces. Force can change the state of motion: An Object can be in two states. Examples - pushing the object like school bag or lift the dumbles for exercising, we use the muscular force.
Learning the important concepts is very important for every student to get better marks in examinations. The concepts should be clear which will help in faster learning. We use force all the time. We use force to open a door, to pick up the school bag, to brush our teeth, to squeeze out toothpaste from a tube, to turn on a tap and so on. Even the earth is exerting a force on us all time.

Force: i Force is a push or a pull. One which applied force, the other which receive force. Examples: To kick ball we need to push it, to pick the book we need to pull it, to hit the ball we need to push it and to lift the box we need to push it.
A push or a pull on an object is called force. Force has both magnitude and direction. The SI unit of force is newton. The motion imparted to objects is due to the action of a force. Forces are due to an Interaction:- At least two objects must interact for a force to come into play.
Force arises due to the interaction between at least two objects. Two friends pushing a heavy load a in the same direction and b in the opposite direction. To move a tyre faster it has to be pushed repeatedly. A magnet can exert a force without being in contact with it.
