Oblique Collision is also termed as two-dimensional collisions or non-head collision. This is because both the bodies have different line of impact before collision.

Let us consider two bodies of mass m_{1} and m_{2} respectively

Initial Velocities are u_{1} and u_{2} respectively as shown in Fig. 7.3

Total momentum before collision in x-direction = m_{1}u_{1} cos_{1} + m_{2}u_{2}cos_{2}

Total momentum after collision in x-direction = m_{1}u_{1}cos_{1}+ m_{2}u_{2}cos_{2}

According to law of conservation of momentum, total momentum (after collision) in x-direction can be written as-

m_{1}u_{1}cos_{1}+ m_{2}u_{2}cos_{2}= m_{1}u_{1}cos_{1}+ m_{2}u_{2}cos_{2}
