Similarly, when opposite poles of a magnet repel each other we can say that they are pushing each other away. When two forces act in the same direction, the net resultant force on an object is the sum of these two forces.

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. Once you study this chapter, you will understand how vast this concept will become in the next classes. Follow the Science Class 8 Chapter 11 notes to find a simple revision note on the definition and explanation of force.

Force and Pressure Class 8 Notes Science Chapter 11

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. Thus, an interaction of one object with another object results in a force between the two objects.

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. The force exerted by a magnet is an example of a non-contact force.

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.

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.

Или это его подвинули. Голос все звал его, а он безучастно смотрел на светящуюся картинку. Он видел ее на крошечном экране. Эту женщину, которая смотрела на него из другого мира.

Фонтейн, которого он знал, был внимателен к мелочам и требовал самой полной информации. Он всегда поощрял сотрудников к анализу и прояснению всяческих нестыковок в каждодневных делах, какими бы незначительными они ни казались. И вот теперь он требует, чтобы они проигнорировали целый ряд очень странных совпадений.

Всего двадцать минут, подумала. Повернувшись к терминалу Хейла, Сьюзан вдруг уловила странный мускусный запах - очень необычный для Третьего узла. Она подумала, что дело, быть может, в неисправном ионизаторе воздуха.
