in case of rolling without slipping of a solid sphere having uniform mass density the condition is
Vcm (velocity of center of mass ) = Rω or [a][/cm] = Rα ,which comes from the fact that if an object that rolls without slipping the geometric center of the body travels 1 circumference along...
same confusion here in order to find the torque because of the weight we should consider weight to be acting about center of mass ( i.e center of gravity ) which is at (2r/pi , 2r/pi) but Kleppner has taken weight to be acting about the middle point on the rod which is on rod itself.
in defining the Equation of simple harmonic motion taking origin as fixed point and the line of motion as x axis. a(acceleration) = - w^2 * x. where w^2 is positive constant. what is the reason behind taking square of w as constant not just w?
when the body rotates with uniform motion then the normal acceleration is V^2/r. but what is the normal acceleration when the motion is in non uniform circular motion let's say when body has uniform tangential acceleration.
why triple point of water is used to define SI base unit of thermodynamic temperature even though for triple point we need to define both temperature (. 01) and pressure(partial pressure = 611.73 pa). this thing we can do with ice point and boiling point which is same when temperature and...
