(i) Units and dimensions : Units of measurement, system of units, fundamental and derived units, S I units, dimensional analysis.
Methods of measurement: Vernier scale, screw gauge, analysis of errors, significant figures.
(ii) Scalars and vectors: Addition, subtraction, multiplication of vectors.
(iii) Kinematics in one, two and three dimensions, projectiles, uniform circular motion,centripetal force, centrifigual force, relative velocity.
