JEE ORIENTATION CLASS MECHANICS LEC 1INTRODUCTION1 Whats itIt is basically something dependent on Newton’s laws of motion. We mainly study the motion of things.2 Where is itHCV I Ch 1 to 14NCERT BOOK 1 CLASS 113 How much marks30% to 40% of JEE PaperProofJEE 2013 PAPER 1 JEE 2013 PAPER 2Q1 Cllision + projectile Q1 GravitationQ2 Errors Q2 Spring +collisionQ3 Work energy Q3 FrictionQ4 Rotaton Q4 EnergyQ5 Work energy + Circular motion Q5 DimensionsQ6 Spring force +buoyancyQ7 Work energyTOTAL 7 Que out of 21 Total 5 Q out of 21

PHYSICS AND MATHEMATICS CH 2The connection of Physics and Maths2.1 VECTORS AND SCALARSWhat are vectorsHow they are shown on paperBy the way we learn how to add displacementsAnd velocities2.2 EQUALITY OF VECTORSThat is a vector can be translated parallel to itself.2.3 ADDITION OF VECTORSThe triangle rule

Glide a or b to put a’s head in b’s tail now join a’s tail to b’s head to get a+b.Some practiceThe formula

The other variants the POLYGON LAW and PARALLELOGRAM LAW
