unbalanced forces

An unbalanced force acting on an object changes its speed or direction. The resultant of unbalanced forces is always greater than zer..

The figures show a block of wood on a table. When the block is pulled at point A, it begins to move towards the left and if the block is pulled at the point B it moves towards the right. Example of Balanced Forces In a game of tug of war when both the teams pull the rope with equal and op..

A force is often defined as a "push" or a "pull". There is nothing untrue with this statement, but does not really tell you much about a force. Instead of defining force, it substitutes an antonym. A physicist prefers to define a force in terms of what it doe..

Simple Pendulum and Restoring Force - In the previous chapters we studied the motion of a body moving with uniform speed in a straight line and also learnt to calculate the distance traveled by a body in any given time. We then observed that the bodies do not always move with uniform spee..

Forces Acting on the Bob of a Simple Pendulum - The bob of a simple pendulum is attached to a string which pulls the bob along its lengt..

Question: What are balanced and unbalanced forces? Answer: Balanced forces are those forces whose resultant is zero. Unbalanced forces are those forces whose resultant is not equal to zero..

Pushes or Pulls are very general names given to forces. A physicist is much more precise when describing forces acting on a body using terms like weight, frictional force, tension, normal reaction force, electrical force, magnetic force et..

Summary - Inertia is the inability of material body to change, by itself, its state of rest or of uniform motion in a straight line. Mass is a measure of inertia Newton's first law of motion: A body continues in its state of rest or of uniform motion along a straight line unless an external un..

Adsorption - Adsorption is a surface phenomenon. In this process, accumulation or concentration of a substance takes place at the surface or interface as compared to the bulk phases. This happens because the molecules of the bulk phase at the surface are attracted only from below and from the sides..
