Inelastic Collision in Two Dimensions | 1st Year Physics Chapter 2 | Handwritten Notes
Complete handwritten notes on *Inelastic Collision in Two Dimensions* from 1st Year Physics Chapter 2. *Key Points Covered:* Inelastic collision is observed at macroscopic level. In this type of collision, *Momentum is conserved but Kinetic Energy (K.E) is not conserved*. *Explanation & Derivation Included:* A system of two balls with masses m1 and m2 is considered. m1 moves along x-axis with velocity V1 and m2 moves in XY-plane at angle θ. After collision, both stick together and move as a single mass M = m1 + m2 with velocity Vf at angle φ. *Conservation of Momentum:* - Along X-axis: m1v1 + m2v2 cosθ = M Vf cosφ - Along Y-axis: m2v2 sinθ = M Vf sinφ These two equations are used to find final velocity Vf. *Energy Loss:* (K.E)i = 1/2 m1v1² + 1/2 m2v2² (K.E)f = 1/2 M Vf² Loss in K.E = (K.E)i - (K.E)f, this loss appears as heat, sound etc. Notes include a clear diagram and are best for FSc and One Paper preparation with easy-to-understand handwriting.
