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
Rocket Propulsion The propulsion of a rocket is an example of momentum conservation. In a rocket, gases at high temperature and pressure, are produced by the combustion of fuel. They escape with a large constant velocity through a nozzle. The large backward momentum of the gases imparts an equal forward momentum to the rocket. But … Read more
Friction Whenever a body moves or tends to move over the surface of another body, a force comes into play which acts parallel to the surface of contact and opposes the relative motion. This opposing force is called friction. Angle of friction The angle of friction may be defined as the angle which the resultant … 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
Momentum Momentum of a body is the quantity of motion possessed by the body. It is equal to the product of mass and velocity of the body. Momentum = Mass × velocity = mv Momentum is a vector quantity because the velocity is a vector and mass m is a scalar. Its direction is same … 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
