Superposition Principle of Waves
When two or more wave motions traveling through a medium superimpose one another, a new wave is formed whose resultant displacement at any instant is equal to the vector sum of the displacement due to individual waves at that instant The two short lined waves traveling in opposit..

It should be borne in mind that the uncertainty is not due to lack of sufficiently refined techniques but it is due to the fact that one cannot observe microscopic things without disturbing them. No instrument can observe the position of an electron without affecting its motion. In ..
Motion in a Vertical Circle
Motion in a Vertical Circle - Consider a body of mass 'm' tied to a string and rotated in a vertical circle of radius 'r'. The velocity (speed) of the body keeps changing. It is maximum at the bottom and a minimum at the to..

Every body continues in its state of rest or of uniform motion in a straight line unless compelled by some external force to act otherwise. It is a matter of common experience that objects at rest do not begin to move of their own accord. If we place an object in a certain place we expect..
Motion of Particles and Rigid Body Summary
Summary - The centre of mass is an imaginary point where one can assume the entire mass of the given system or object to be positioned. Principle of conservation of linear momentum states that the linear momentum of a system remains constant if the external forces acting on the system add..
Momentum Conservation and Motion of Centre of Mass
>Hence, the principle of conservation of linear momentum states that the linear momentum of a system remains constant if the external forces acting on the system add up to ze..
Oblique projectile
If a body is projected at a certain angle with the horizontal, then the body is called an oblique projectile. The motion of a projectile is a two dimensional motion. So it can be discussed in two parts Horizontal motion Vertical motion These two motions..
Fleming's Right Hand Rule
The direction of the current in a wire moving perpendicular to itself and to a magnetic field may be found by Fleming's right hand rule. If the thumb, forefinger and middle finger of the right hand are stretched in a mutually perpendicular direction, in such a way that the forefinger directs towar..
The two balances show the same reading because the action force equals the reaction force.
. In the first experiment, when two spring balances are pulled in opposite directions, they experience the same force acting in the opposite directions. In case of the balloon when you release it, the air inside the balloon rushes out downward, exerting force on the air outside. The balloon experie..

Comparison between Progressive Waves and Stationary Waves - Progressive waves Stationary waves The disturbance produced in the medium travels onward, it being handed over from one particle to the next. Each particle executes the same type of vibration as the preceding one, though not at the same ti..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
