mole of an ideal gas be heated at constant volume. The heat supplied is .By the First Law of Thermodynamics:

Tips to Score Full Marks in Derivations

Derived directly from Newton’s Second and Third Laws.According to Newton's Third Law, the action and reaction forces between two colliding bodies ( ) are equal and opposite:

m1(u1−v1)=m2(v2−u2)--- (Equation 1)space m sub 1 open paren u sub 1 minus v sub 1 close paren equals m sub 2 open paren v sub 2 minus u sub 2 close paren space --- (Equation 1) 2. Conservation of Kinetic Energy The heat supplied is

Practice checking formulas by setting conditions to zero (e.g., setting banking angle

Kinematics describes the motion of points, bodies, and systems without considering the forces that cause them to move. 1. Equations of Motion (Calculus Method)

Class 11 Physics forms the bedrock of both board exams and competitive entrance tests like JEE and NEET. While understanding concepts is crucial, mastering derivations is the secret to scoring full marks. Derivations explain the "why" and "how" behind formulas, transforming rote memorisation into logical understanding. 1. Conservation of Linear Momentum

v2−u22=as⟹v2=u2+2asthe fraction with numerator v squared minus u squared and denominator 2 end-fraction equals a s ⟹ v squared equals u squared plus 2 a s Projectile Motion

For a streamline, non-viscous, incompressible fluid flow, the sum of pressure energy, kinetic energy, and potential energy per unit volume remains constant. Consider a pipe with varying cross-sections at heights .Work done on the fluid entering at end 1: Work done by the fluid leaving at end 2: Net work done:

): Acceleration is defined as the rate of change of velocity:

v1=(m1−m2m1+m2)u1+(2m2m1+m2)u2v sub 1 equals open paren the fraction with numerator m sub 1 minus m sub 2 and denominator m sub 1 plus m sub 2 end-fraction close paren u sub 1 plus open paren the fraction with numerator 2 m sub 2 and denominator m sub 1 plus m sub 2 end-fraction close paren u sub 2

This unit deals with the causes of motion, introducing forces, friction, and circular dynamics. 1. Conservation of Linear Momentum
