Laws of motion

  1. 1. Newtons Law of Motion● Newton has givenThree Laws ofMotion to define themotion of bodies.● These Laws areknown asNewtons Laws ofMotion
  2. 2. Newtons First Law ofMotion● A body at rest will remainin rest, and a body inmotion will continue inmotion in a straight linewith uniform speed,unless itis compelled by an externalforce to change its state ofrest or of uniform motion.● INERTIA: Inertia is thatproperty of a body due towhich it resists a change instate of rest or of uniformmotion
  3. 3. Newtons Second Law ofMotion● The rate of change ofmomentum of a body isdirectly proportionalto applied force andtakes place in thedirection in whichforce acts.● Force = change inMomentum/TimeTaken● Its S.I. Unit is Newton
  4. 4. Newtons Third Law ofMotion● The law that, if twoparticles interact, theforce exerted by the firstparticle on the secondparticle is equal inmagnitude and oppositein direction to the forceexerted by the secondparticle on the firstparticle .● To every action there isequal & opposite reaction
  5. 5. Conservation ofMomentum● When two or more bodiesact upon one another ,their total Momentumremains constantprovided no externalforces are acting.● Momentum is neithercreated nor destroyed butit is conserved.● Total Momentum beforecollision = TotalMomentum aftercollision
  6. 6. Conservation ofMomentum● When two or more bodiesact upon one another ,their total Momentumremains constantprovided no externalforces are acting.● Momentum is neithercreated nor destroyed butit is conserved.● Total Momentum beforecollision = TotalMomentum aftercollision
