1.	Express Newton's second law of motion in component form. Give its significance.
Answer» SOLUTION :Intermsof cartesiancoordinates , thisequationcan bewritten as Bycomparingbothsidesthe three scalar equationare Theaccelerationalongthe ydirectiondepends only on thecomponentof forceactingalong the y -DIRECTION `f_(y) = ma_(y)` Significance: From the aboveequationsit isinferredthat theforceactingalong ydirectioncannotalterthe accelerationalong x direction. In the SAMEWAY `F_(z)` cannotaffect`a_(y)` and `a_(x)`
