MECHANICS
Important notes for IOE,AFU ,CEE, PU , TU
CHAPTER- 2 Scalar and Vector
Basic to Remember ( Most asked Question)
- Pressure , surface tension,current etc are scalar
- Linear momentum,acceleration,displacement,momentum,angular velocity,force,electric field, polarization etc are vector
- Moment of inertia, stress,strain,refractive index,relative humidity,resistance,coefficient of viscosity etc are neither vector nor scalar
- To give zero resultant , minimum number of
Collinear vectors of equal magnitude = 2
Collinear vectors of uneqal magnitude =3
Coplanar vector=3
Non-coplanar vector =4
