Conservation of Momentum

Momentum for Class-XI By Yatendra Kumar

Momentum defined ,[object Object],[object Object],[object Object],[object Object],[object Object]

Difference between KE and Momentum kinetic energy … momentum … is a scalar. is a vector is not changed by a force perpendicular to the motion, which changes only the direction of the velocity vector. is changed by any force, since a change in either the magnitude or the direction of the velocity vector will result in a change in the momentum vector. is always positive, and cannot cancel out. cancels with momentum in the opposite direction. can be traded for other forms of energy that do not involve motion. KE is not a conserved quantity by itself. is always conserved in a closed system. is quadrupled if the velocity is doubled. is doubled if the velocity is doubled.
