Equilibrium of concurrent forces Forces acting at the same point on a body are called concurrent forces. When a number of forces act on a body at the same point and the net unbalanced force is zero, the body will continue in its state of rest or of uniform motion along a straight line and … Read more
Solving problems in mechanics: Use of free-body diagram When a number of bodies are connected together by strings, rods, etc, it is convenient to consider each body separately and to write equation of motion for each body by taking into account all the forces acting on it and then equating the net force acting on … Read more
Law of conservation of linear momentum The second and third laws of motion lead to one of the most important and fundamental principles of physics, called the law of conservation of linear momentum. It can be stated as follows: When no external force acts on a system of several interacting particles, the total linear momentum … Read more
Impulsive force: A large force acting for a short time to produce a finite change in momentum is called an impulsive force. Examples: (i) Force exerted by a bat while hitting a ball. (ii) Blow of a hammer on a nail. (iii) Force experienced by a person when he falls from a certain height on … Read more
The Latin word capilla means hair. A tube of very fine (hair-like) bore is called a capillary tube. When a capillary tube of glass open at both ends is dipped in liquid which wets its walls (e.g., water, alcohol), the liquid rises in the tube. But when the capillary tube is dipped in a liquid … Read more
