Science chapter 8 class 8 solution- What is force ?
Force is a fundamental concept in physics that represents a push or pull on an object. It is an interaction that can cause an object to change its state of motion, speed up, slow down, or change direction. Force is described by several key characteristics:
Forces can be categorized into various types, such as gravitational forces, electromagnetic forces, frictional forces, tension, compression, and more. These forces are fundamental to understanding how objects move and interact with one another, and they are described by Newton’s laws of motion, which provide the foundation for classical mechanics in physics.
Science chapter 8 class 8 solution- Type of forces
Forces are interactions that can cause an object to change its state of motion or deform. There are several types of forces, each with its own characteristics and effects. Here are some common types of forces:
- Gravitational Force: Gravitational force is the attractive force that exists between any two objects with mass. It is responsible for the weight of objects and keeps celestial bodies, such as planets, in orbit.
- Normal Force: The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface and prevents objects from falling through it.
- Frictional Force: Frictional force opposes the relative motion or attempted motion of two objects in contact. It is responsible for the resistance when trying to slide objects on a surface.
- Tension Force: Tension force is a pulling force transmitted through a rope, string, or cable when it is stretched. It acts along the length of the rope and is used in scenarios like lifting objects.
- Applied Force: An applied force is a push or pull exerted on an object by another object. It can be a human applying force to move an object or any external agent applying force.
- Spring Force: Spring force, or elastic force, is the force exerted by a compressed or stretched spring. It obeys Hooke’s Law, which states that the force is directly proportional to the displacement from the spring’s equilibrium position.
- Electromagnetic Force: Electromagnetic forces include electric and magnetic forces. These forces can attract or repel charged objects and are fundamental in electromagnetism and the behavior of charged particles.
- Buoyant Force: Buoyant force is the upward force exerted by a fluid (liquid or gas) on an object submerged or floating in the fluid. It opposes the weight of the object and helps objects float.
- Air Resistance (Drag): Air resistance is the force that opposes the motion of an object as it moves through the air. It depends on the object’s shape and speed.
- Magnetic Force: Magnetic force is the force of attraction or repulsion between magnetic objects. It is associated with the alignment and movement of magnetic domains in materials.
- Nuclear Forces: Nuclear forces are the forces that exist within atomic nuclei and hold protons and neutrons together. They are fundamental to nuclear physics and are responsible for the stability of atoms.
Science chapter 8 class 8 solution- What are contact forces ?
Contact forces :Contact forces are a category of forces that occur when two objects physically interact with each other by coming into direct contact. These forces arise as a result of mechanical contact between objects and can either push or pull them.Contact forces are short-range forces, meaning they act over a limited distance and are most noticeable when objects are in direct contact. Here are some common examples of contact forces:
Science chapter 8 class 8 solution- What are non contact forces ?
Non-contact forces, also known as action-at-a-distance forces, are types of forces that can affect objects without any physical contact between the interacting objects. Unlike contact forces, which require direct interaction through physical contact, non-contact forces act over a distance through fields or other mechanisms. Here are some common examples of non-contact forces:

Science chapter 8 class 8 solution-Atmospheric pressure
atmospheric pressure is the force exerted by the air surrounding us and can vary with altitude and weather conditions. It is responsible for various meteorological phenomena, including changes in weather patterns, and plays a role in everyday activities, such as the operation of barometers and altimeters.
Science chapter 8 class 8 solution – Pressure
Pressure is a physical quantity that measures the force applied to an object per unit area. It is a scalar quantity, meaning it has magnitude but no specific direction.
Science chapter 8 class 8 solution – Force
Force is a fundamental concept in physics that represents a push or pull on an object. It is an interaction that can cause an object to change its state of motion, speed up, slow down, or change direction.
Frictional force opposes the relative motion or attempted motion of two objects in contact. It is responsible for the resistance when trying to slide objects on a surface.
