  1. PHYSICS Class XI Pradeep Kshetrapal


  2. Chapter 4. Motion in a plain VECTORS Lesson: XI-4-2 vector addition


  3. Addition: Triangle method Second vector is moved such that its tail coincide with head of the first vector. Then a vector from tail of first to head of second gives resultant vector , or addition of two. Adding 2 Vectors


  4. Addition : Triangle method-another example Second vector is moved such that its tail coincide with head of the first vector. Then a vector from tail of first to head of second gives resultant vector, or addition of two. Adding 2 Vectors

  9. Addition by parallelogram Two vectors A and B of magnitude a and b, inclined at angle are acting at a point O. If these vectors are represented by two sides of a parallelogram then resultant i.e. addition is represented by the diagonal passing through O. R ABO The magnitude of this resultant is equal to r, the length of OQ which is equal to rON+ ON2 a sine M a cose N If a is the angle made by resultant then it is given by relation -OM MN +20M.MN +QN MMN2 2OM.MN +QN tan b acose Pradeep Kshetrapal


  10. Minimum condition for addition The two quantities should have the SAME NATURE i.e.Velocity can be added to velocity and not with force.


  11. Special cases of addition 3.When two vectors are at right angle to each other angle between them is 90 Cos 90 is 0 (a) Velocity Airplane4 (b) velocity of air3 -r resultant 5


  12. Components of a vector, Vector B is | effective in both axis the directions. Its effect in x direction is given X-akis by Bx. And |effect in Y direction is given by By Pradeep 6a comp.avi
