# Laws of Forces

## Causes of Friction

What are the causes of Friction? Friction is a natural phenomenon which resists the motion of a solid material body upon another solid surface or liquid mass or gaseous atmosphere. Different theories are available whichRead More →

## Centre of Mass of Cone

Centre of Mass of a Solid Cone A solid cone may be considered to be constructed of numerous tiny particles. These tiny particles have their own masses. Hence, the total mass of the cone isRead More →

## Centre of Gravity

What is meant by Centre of Gravity? Centre of gravity of a body is a fixed point where total weight of body is assumed to be concentrated. It is the point through which, force ofRead More →

What is called Addition of Forces? A body may be subjected upon various forces acting simultaneously upon it. It is very cumbersome and difficult to analyze the effect of each force separately. So, these forcesRead More →

## Friction on Inclined plane

How Friction acts on Inclined Plane? Friction on an inclined plane depends upon the angle of inclination of the plane. As the angle of inclination increases, the friction force decreases. To understand this, consider aboutRead More →

## Laws of Friction

What are Laws of Friction? Friction is a natural phenomenon which resists the motion of a solid material body upon another solid surface or liquid mass or gaseous atmosphere. Therefore, if there is a relativeRead More →

## Types of Frictional Force

What is Frictional Force? Friction is a natural phenomenon which resists the motion of a solid material body upon another solid surface or liquid mass or gaseous atmosphere. Therefore, if there is a relative motionRead More →

## Principle of Moment

What is the Principle of Moment? Principle of moment states that – If a number of co-planer forces are in static equilibrium, then the algebraic sum of their moments about any point in their planeRead More →

## Moment of Force

What is Moment of a Force? If a body is free to move and a force is applied on that body, then the effect of this force will produce some action or movement in theRead More →

## Lami’s Theorem

What is Lami’s Theorem? In analyzing of the force problems, sometimes we require to evaluate the effect of a force in a certain direction of our interest. This is done by resolving the forces inRead More →

## Resolution of Forces

What is called Resolution of Forces? In analyzing the force problems, sometimes we require to evaluate the effect of a force in a certain direction of our interest. This is done by resolution of forcesRead More →

## Mass and Weight

What is called Mass of a body? Mass is a quantitative measure of matter content of a body which produce inertia. It is a fundamental property of all matter bodies. It offer a resistance inRead More →

## Fundamental Forces

What is a Force? A force is defined as an agent i.e. a push or a pull which keep a system in working condition. The concept of force was first developed by Sir Isac Newton.Read More →

## Centre of Mass of Hemisphere

How to find Centre of Mass of Solid Hemisphere? A solid hemispherical body may be considered to be constructed of numerous tiny particles. These tiny particles have their own masses. Hence, the total mass ofRead More →

## Centre of Mass

What is called Centre of Mass? The whole mass of a body may be assumed to be concentrated at a fixed point. This fixed point at which the whole mass is assumed to be concentrated,Read More →
