Force and Pressure Class 8 Notes Science Chapter 11

January 24, 2024 by Sastry CBSE

CBSE Class 8 Science Notes Chapter 11 Force and Pressure Pdf free download is part of Class 8 Science Notes for Quick Revision. Here we have given NCERT Class 8 Science Notes Chapter 11 Force and Pressure.

CBSE Class 8 Science Notes Chapter 11 Force and Pressure

A push or pull exerted by an object on another is a force.

Force arises due to the interaction between at least two objects.

Force has both Magnitude and Direction

  • Force applied on an object in the same direction add to one another.
  • If the two forces act in the opposite direction on an object, the net force acting on it is the difference between the two forces.
  • In general, more than one force may be acting on an object at any given point. However, a force acting on an object is always the mean net force acting on it.

A Force can Change the State of Motion

  • A change in the speed of an object or the direction of its motion or both implies a change in its state of motion.
  • Force acting on an object may bring a change in its state of motion or a change in its shape.

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.

Thrust: The force that acts on a surface in a direction perpendicular to it, is known as thrust.

Pressure: Thrust per unit area is called pressure. So, pressure = force/area on which it acts.

Liquids exert pressure on the walls of the container in which they are kept.

Gases exert pressure in all directions.

Electrostatic force: A force exerted by a charged body on another charged or uncharged body is known as electrostatic force.

Atmospheric pressure is defined as the pressure exerted on a surface by the weight of air above that surface.

Atmospheric Pressure: The pressure exerted by atmospheric air around us is known as atmospheric pressure.

Contact Force: A force that can be applied only when it is in contact with an object is called a contact force. For example, hammering a nail.

Electrostatic Force: When a charged body, either having a (+) or (-) charge, exerts force on another charged or uncharged body, that force is known as electrostatic force.

Force: Simply a push or pull exerted by an object on another is a force.

Friction: The force of friction always acts on all the moving objects and its direction is always opposite to the direction of motion.

Gravitational Force: The force exerted by the earth to pull the objects towards itself is called the force of gravity.

Gravity: Every object in the universe, whether small or large, exerts a force on every other object. This force is called the force of gravity or just gravity.

Magnetic Force: The force exerted by a magnet to pull/push a metallic object is called magnetic force.

Muscular Force: The force resulting due to the action of muscles is known as muscular force. For example, writing, cutting vegetables.

Non-Contact Forces: A force that can be applied without any contact between two objects is called non-contact force. For example, the magnet pulls the iron-pieces.

Pressure: The force acting on per unit area, applied to an object in the direction perpendicular to the surface is called pressure.

We hope the given CBSE Class 8 Science Notes Chapter 11 Force and Pressure Pdf free download will help you. If you have any query regarding NCERT Class 8 Science Notes Chapter 11 Force and Pressure, drop a comment below and we will get back to you at the earliest.
