One dyne
One dyne is the force which produces an acceleration of 1cm/s 2 in a body of mass 1gram. 1 dyne = 1 gm x 1cm/s 2 The relation between one dyne and one Newton is 1 N = 10 5 Dyne or 1 Dyne = 10 - ..
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 position. For this, we need to know the position coordinates. In some cases, three position coordinates are required, in some ca..
One kilogram weight of force
is the force with which a body of mass 1kg is attracted towards the centre of the Earth. 1 kg wt = 1 kg x 9.8m /s 2 = 9.8N The gravitational system is easier to comprehend and visualise than the absolute system, but the only flaw is that the value of 'g' is not a co..

Thus, if one joule of work is done in one second by any agent then its power is said to be one watt.
Kilowatt and megawatt are higher units of power. 1 kilowatt (KW) = 10 3 watts 1 Megawatt (MW) = 10 6 watts Another unit of power is horse power (h.p) 1 h.p. = 746 wat..
Work done by a variable force (one dimensional case)
Let us consider a situation where the force is acting along the X-axis and the magnitude of the force is varying with position 'x'. Thus, as the ball moves, the magnitude of the work done by the force, on the ball, changes. The adjacent graph shows the plot of a one dimensional variable ..

A Karate expert strikes a board of mass 0.14 kg and breaks it, with his fist of mass 0.70 kg. He then does the same to a 3.2 kg concrete block. The spring constant 'k' for bending are, 4.1 x 10 4 N/m for the board and 2.6 x 10 6 N/m for the block. Breaking occurs at a deflection 'd' of 16..

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.
Unlimited tutoring for 24/7 in all the subjects, It's a great help for my kids.
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.
I have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
Looking for More Help!
