Hm. Its better you once go through all the MIT notes and Video lectures of Walter Lewin ! I'm sure you can get a better knowledge about it !
To understand anything you have to deal with it ,so make experiments or just watch different videos which show demonstration about circular motion. You can be specified and ask which kind of circular motion Is it uniform or not? What is your confusion about circular motion?
Okay I will check out the MIT videos!! Thanks!! I tried checking out youtube videos but I dont seem to find any good ones. Any recommendation besides the MIT videos?? My confusion about circular motion is the whole basics of it. My lecturer told me that it is some how similar to kinematics eventhough it uses different unknown but you have to look at it in a circular overview and I dont seem to get the grabs out of it. Any suggestions to helping me understand it???
How do i know when to use the elastic formula or conservation of momentum formula. I get pretty mixed up when im doing physics. I get confused by the fact that even though the question states that its an elastic motion, I do not use the elastic formula but use the conservation of momentum formula to get the right answer. If I use the elastic motion formula I will then get the wrong answer. please explain to me why is this so?? And the principle behind it. Thank you very much. I am in need of your help as finals is coming up. :)
read text books with full concentration and i prefer resnick and hallidayphysics book its the best phy book
For the circular motion you can watch this http://ocw.mit.edu/courses/physics/8-01-physics-i-classical-mechanics-fall-1999/video-lectures/lecture-5/ conservation of momentum is the general law when their is NO EXTERNAL FORCE exists and elastic formula is conservation when it is elastic and i think you confused with that you use formula of linear elastic collision in 2 dimension problem ,so you get the wrong answer. You have to make it for direction of Y then of X and get the resultant. If i got it wrong write down the problem.
circular motion is similar to straight motion but you have to change x with theta the angel by radian you can use all the straight motion equation with easy modification theta instead of x but be careful if the tangential speed is constant there is no radial acceleration alpha but there is central acceleration due to the change in direction of velocity
circular motion is defined as the motion along a curved path where the velocity direction is always at the tangent of the curve can be divide as uniform and non uniform circular motion
