derive all equation of motion mathametically & graphically.

Answer 1

Since this is not my area of expertise, I searched Google under the key words "motion equation" to get these possible sources:

http://en.wikipedia.org/wiki/Equation_of_motion
http://hyperphysics.phy-astr.gsu.edu/Hbase/mot.html
http://www.ac.wwu.edu/~vawter/PhysicsNet/Topics/Kinematics/ConstantAccEqMotion.html
http://trond.hjorteland.com/thesis/node21.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
