During inclined collision of two particle

In one dimeensional collision of two particles velocities are interchanged when (a)Collision is elastic and masses are equal (b)Collision is inelastic but masses are unequal

During elastic collision

The principle of conservation of linear momentum can be strictly applied during a collision between two particles provided the time of impact is

During elastic collision of two balls, is kinetic energy conserved during the short interval of contact of balls ?

During elastic collision of two balls, is kinetic energy conserved during the short interval of contact of balls ?

In a one-dimensional collision between two particles, their relative velocity is vecv_(1) before the collision and vecv_(2) after the collision
