  • 1. Newton's Laws of Motion Cut and discard this bottom portion.
  • 2. Newton’s First Law
    • An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force .
    • Also called the law of inertia
    The greater an object’s mass, the greater its inertia, and the larger the force needed to overcome the inertia. Newton’s 1 st law Cut and discard this bottom portion.
  • 3.
    • car suddenly stops and you strain against the seat belt because our bodies want to keep moving
    • the difficulty of pushing a dead car
    • car turns left and you appear to slide to the right
    • ketchup stays in the bottom (at rest) until you bang (outside force) on the end of the bottom
    • a headrest in a car prevents whiplash injuries during a rear-end collision (your head goes forward and then jerks backward)
    Examples of Newton’s 1 st Law Examples of 1 st law Cut and discard this bottom portion.
  • 4. Newton’s 2 nd Law F = M x A
      • The greater the force, the greater the acceleration
      • The greater the mass , the greater the force needed for the same acceleration
      • Calculated by: F = ma
      • (F = force, m = mass, a = acceleration)
    Newton’s 2 nd Law Cut and discard this bottom portion.
  • 5. Examples of Newton’s 2 nd Law
    • hitting a baseball, the harder the hit, the faster the ball goes
    • accelerating or decelerating a car
    • The positioning of football players –
    • massive players on the line with lighter
    • (faster to accelerate) players in the
    • backfield
    • a loaded truck versus an unloaded truck
    Examples of 2 nd Law Cut and discard this bottom portion.
  • 6. Newton’s 3 rd Law
        • For every action force, there is an equal and opposite reaction force. (Forces are always found in pairs .)
    • Athlete pushes bar upwards.
    • Bar pushes the athlete downwards.
    • Bowling ball pushes pin to the right.
    • Pin pushes bowling ball to the left.
    Newton’s 3 rd Law Cut and discard this bottom portion.
  • 7. Examples 3 rd Law
    • Momentum of the car moving forward and the car comes to a sudden stop, our body pushes against the seat (action) belt and the seat belt pushes back (reaction).
    • When you lean on the wall to rest, the weight on the wall provides the reaction force and the wall pushes back on you (reaction force) with the same force.
    • Roller coaster ride- The train to the tracks.
    • Birds wings to the air.
