Atmosphere pressure – അന്തരീക്ഷമർദ്ദം
Atmospheric pressure is the pressure exerted by the atmosphere of Earth (or that of another planet) on the surface of that planet. It is generally measured in millibars (mbar) or hectopascals (hPa).
Liquid pressure – ദ്രാവകമർദം
Liquid pressure is the pressure exerted by a liquid on the walls of its container due to the force of gravity. The pressure is caused by the weight of the liquid. The pressure increases with depth as the weight of the liquid above the point of measurement increases.
Weight – ഭാരം
Weight is a measure of the gravitational force of attraction between objects, and is usually expressed in units of mass (e.g. kilograms or pounds). Weight is related to mass, but the two are not the same. Mass is an intrinsic property of an object, while weight depends on the strength of the gravitational force between …
Thrust and pressure – വ്യാപകമർദവും മർദവും
Thrust is a force that propels an object forward. It is generated by the reaction of a system that pushes an object in a specific direction. Pressure is the force applied perpendicular to the surface of an object per unit area. It is calculated as the force divided by the area. Thrust is a force …
State the method for reducing the friction – ഘർഷണം കുറയ്ക്കുന്നതിനുള്ള രീതി
Use lubricants: Lubricants reduce friction by forming a thin layer between two surfaces, reducing the direct contact between them. Increase the surface area: Increasing the surface area of the two surfaces in contact reduces the friction because it allows the force to be spread more evenly over the surface, reducing pressure. Use ball bearings: Ball …

The car, plane designed in a peculiar shape – കാറും വിമാനവും ഒരു പ്രത്യേക ആകൃതിയിൽ രൂപകൽപ്പന ചെയ്തിരിക്കുന്നത്
The shape of a car or plane is designed to be aerodynamic and efficient. An aerodynamic shape reduces drag, allowing the vehicle to move more efficiently through the air or water. Additionally, the shape of a car or plane affects the way it handles and performs. The design of the vehicle can help ensure passengers …
Different type of friction – വ്യത്യസ്ത തരം ഘർഷണം
1. Static friction: This is the friction that resists movement when two objects are not moving relative to each other. 2. Sliding friction: This is the friction that resists movement when two objects are moving relative to each other. 3. Rolling friction: This is the friction that resists movement when an object rolls along a …

Frictional force – ഘർഷണ ബലം
Frictional force is the force which resists the relative motion between two objects in contact. It is a non-contact force and is the result of the electromagnetic forces between the particles of the two surfaces. Frictional force acts in a direction opposite to the motion of the object and its magnitude is proportional to the …
Contact force and non contact force – സമ്പർക്കബലവും സമ്പർക്കരഹിതബലവും
Contact forces are physical interactions between two objects that are in physical contact with each other. Examples of contact forces include friction, tension, normal force, and air resistance. Non-contact forces are physical interactions between two objects that are not in physical contact with each other. Examples of non-contact forces include gravity, magnetism, and electric forces.
Different type of force – വ്യത്യസ്ത തരം ബലം
1. Gravitational Force: This is a force of attraction between two objects that is proportional to the product of their masses and inversely proportional to the square of the distance between them. It is the force that keeps us on the ground and keeps the planets in orbit. 2. Electromagnetic Force: This is the force …
