    Confused about Current Flow & Capacitances

    I got it nw... Electron loses potential energy as it moves from low potential to high potenital..!...thnxx...@Nugatory!

    Confused about Current Flow & Capacitances

    I have some doubts regarding Current Flow and Capacitances... I Read this somewhere.. " an electrochemical cell supplies energy to move a charge from its low energy, low potential terminal to the high energy, high potential terminal. In this sense, the cell supplies the energy to establish...

    I'm writing a program that simulates circular

    First of all it depends on the type of collision ..whether it is elastic, inelastic or partially elastic...The velocity vectors of both the balls ( for ex.) can be resolved in a direction perpendicular and parallel to the common normal or what we call line of impact of both balls...IN CASE if u...

    Rotational Dynamics Confusion

    ...and that's why particles other than COM have angular velocity while COM only translatesBy this I meant that when we study motion w.r.t COM, then COM will only have translational velocity whereas all other particles will have velocity = Vcm + w.R ...and COM will have no tangential velocity as...

    Rotational Dynamics Confusion

    @tiny-tim THnxx... Ok. So Since in most of the cases Bodies rotate along the COM axis ..that's why we study rotation with respect to COM...and that's why particles other than COM have angular velocity while COM only translates...More over its easy to calculate Moment of Inertia along COM...

    Rotational Dynamics Confusion

    So here we study the motion of centre of mass of the body and letz say it has a velocity Vcm ..then we know that the whole body has a translational velocity Vcm... But letz say that at some instant i obtained the net velocity of a particle say V...then the translational velocity of the body...

    Rotational Dynamics Confusion

    I knw that all the particles move with the same velocity...But can it be different than that of Vcm ...In case if COM is outside the body..?

    Rotational Dynamics Confusion

    I am right now studying Rigid Body dynamics.. I have some doubts regarding Dynamics... 1) When a body is rotating as well as translating...we say that every particle of the ..lets say ROD is moving with a resultant velocity = Vcm ( translational velocity of COM) + ω.R (where R is the...

    A Case Of Momentum Conservation

    Thnx...@Soothsayer... I got it now...Since, Earth has very large mass as compared to the ball...its vel. is negligible...and that's why when we give the velocity back to the ball... So whenever we conserve momentum along y direction ...it is understood that (objects + earth) has been taken as a...

    A Case Of Momentum Conservation

    My question is... when a ball falls vertically on an inclined plane with a velocity [v][/0] and let it collide elastically with the incline plane...let the angle of inclination be 'β' ... Now, here we conserve the momentum of the ball in the direction of commomn normal of the two...

    Working with Springs: What Happens When Mass m1 is Pushed?

    The suraces are frictionless and the spring is massless...both the masses will surely accelerate... @haruspex : I could not write equation ... Im not able to understand what is going to happen if we exert a force on m1...wat the spring will do after that...

    Working with Springs: What Happens When Mass m1 is Pushed?

    But we can still relate the accelerations of m2 with that of m1..can't we??.. F is a steady force...

    What is the relationship between velocity and acceleration?

    First of all.. we can use v = u + at only when acceleration is constant... when u have acceleration data every second..and if it is changing then u cannot apply the equation s = ut + 1/2 at2 for a comparatively wide range of time interval like 1 second as the acceleration is changing every...

    Working with Springs: What Happens When Mass m1 is Pushed?

    Spring force always creates a doubt in my mind... My question is that.. When two masses say m1 and m2 are connected to each other via a massless spring... m2 is ahead of m1... if we push the block m1 towards m2 ..say with a force F..then what exactly will happen?? What i think is that...
