Assignment 4.3 | Class 11 Physics Chapter 4 Work and Energy | Federal Board KP Board| Study with ME Class 11 11th Class 1st Year Physics Chapter 4 Work and Energy Assignment 4.3 Work and Power Federal Board KPK Board Assignments Khyber Pakhtunkhwa Textbook board Peshawar Balochistan Textbook board Quetta Relation between Momentum and Kinetic Energy Loss in Potential Energy Gain in Kinetic Energy Work done by Friction Work done against friction Loss of P.E = Gain in K.E Loss of P.E = Gain in K.E + Wf Consider a person on a sled sliding down a 100 m long hill on a 30o incline. The mass is 20 kg and the person has a velocity of 2 m/s down the hill when they are at the top. (a) How fast is the person travelling at the bottom of the hill? (b) If the velocity at the bottom of the hill is 10 m/s, because of friction. How much work is done by friction? #Assignment4.3 #Chapter4 #WorkandEnergy #Physics #Class11 #1stYear #Studywithme #ArmyPublicSchool #Work #Energy #LossofPE #GainofKE #PotentialEnergy #KineticEnergy Note: This Channel is for Education Purpose Only.
