Elasticity and Deforming Forces
Elasticity and Deforming Forces - External forces acting on a body, bring about a change in its state or configuration. The latter is possible when the body is not free to move, but the molecules are compelled to change their positions. Such forces are called deforming forces. These force..
Young's Modulus of elasticity
It is defined as the ratio of normal stress to the longitudinal strain within elastic limit. F is the normal force applied at the end of its wire, A is area of cross section (= p r 2 ), D l is the extension produced due to normal force, L is the original length of the wir..

Motion in one dimension
It is also known as rectilinear or linear motion. A particle moving along a straight line is said to undergo one dimensional motion. In such a case, only one of the three rectangular coordinates changes with time. For example, if we consider one dimensional motion alo..

A body is said to be in motion if its position changes with respect to its surrounding. In order to completely describe the motion of such objects, we need to specify its positio..

Motion in two dimensions
A particle moving along a curved path in a plane has two dimensional motion. The figure below, illustrates a two dimensional motion, where a particle moves from P (x 1 , y 1 ) to Q (x 2 , y 2 ) along a curved path. The bob oscillates along a curved path if the simple pend..

I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
The tutor remembered me from last week and noted my improvement. This is simply amazing :)
I could not get time to help my daughter with her homework so I looked on net about online tutoring, we tried tutorvista for a week, my daughter liked it, so, now I got her join it.
Looking for More Help!
