    Position Vectors in Physics: r=(x,y,z) to r=xi+yj+zk

    I did not mean it so simply. It has to do with equations of motion, that they are independent of basis. So any elaboration in this regard would be very much appreciated. Why do the equations of motion become independent of basis when we introduce the i,j,k vectors?

    Position Vectors in Physics: r=(x,y,z) to r=xi+yj+zk

    For describing position of a particle we need vector coordinates r=(x,y,z). But when you go to higher physics like lagrangian formalism also basis vectors are introduced. The position vector then becomes r=xi+yj+zk, where i,j,k are basis vectors. Why do we have do do that? Why is not enough just...

    Understanding Simple Harmonic Motion: Contradicting Acceleration and Velocity

    When observing the acceleration graph of simple harmonic motion we can see that the acceleration is just the opposite of the elongation. Yet we know that the pendulum velocity is increasing when approaching the equilibrium state. Which means that the motion is accelerated altough the sign of the...
