  1. Newton’s Laws of Motion Chapter2 phys102 adilmutlak, yuc

  2. Newton’s First Law (law of inertia) • If = 0, the object stays at rest or stays in motion with constant speed along straight line (constant speed mean “a” = 0) phys102 adil mutlak, yuc

  3. Newton’s Second Law • A net Force produces acceleration • Acceleration is directlyproportional to the net force • Acceleration is in the same direction as the net force • Acceleration is inversely proportional to the mass (m) • When a=g free fall • When a<g non free fall (parachute) phys102 adil mutlak, yuc

  4. Example • Ali exerts a net force of 10.0N on a 6.70 kg shopping cart for 3.0 seconds. Show that the cart has an acceleration of 1.5 m/s2 phys102 adil mutlak, yuc

  5. Weight and Mass • Mass = quantitative measure of inertia; the amount of matter • Weight = force of gravity acting on the mass • Newton's measure of force • Kilogram = measure of mass phys102 adil mutlak, yuc

  6. Example • What is the weight of a 60.0kg person on the surface of earth? • A 60kg person weighs 100.0N on the moon. What is the value of the g on the moon? phys102 adil mutlak, yuc

  7. Newton’s Third Law • To every action there is always an opposed equal reaction phys102 adil mutlak, yuc
