Newton’s laws application

1. 2. LAW OF INERTIA If there is no friction between the tires of the car and ignoring air resistance, a car will run with a constant speed and in straight line continuously.
2. 3. LAW OF INERTIA Seatbelt is provided as safety measures for cars. This is to stop the inertia of the passenger once the car stops.
3. 4. LAW OF ACCELERATION A car moves faster than the truck because according to Newton’s law of acceleration mass is inversely proportional to acceleration.
4. 5. LAW OF INTERACTION As the ball bounces on the floor. The ball exerts a force on the floor at the same time the floor exerts a force on the ball with a force equal in magnitude but different in direction.
5. 6. LAW OF INTERACTION A man walking on the floor moves forward because the floor pushes him forward as the man pushes the floor backward.
6. 7. Newton’s Third Law of Motion <ul><li>Your action caused a reaction. </li></ul><ul><li>Your pushing on the wall caused you to roll backward. </li></ul><ul><li>Newton’s Third Law of Motion states: </li></ul><ul><li>When an object exerts a force on a second object, the second one exerts a force on the first that is equal and opposite in direction. </li></ul><ul><li>AKA – For every action there is an equal and opposite reaction. </li></ul>
7. 8. Action & Reaction <ul><li>When you apply a force on something a reaction occurs. </li></ul><ul><li>When you jump on a trampoline, you exert a downward force on the trampoline. </li></ul><ul><li>The trampoline then exerts an equal upward force on you, sending you into the air. </li></ul>
8. 9. Action & Reaction <ul><li>Remember that action-reaction forces are acting on different objects. </li></ul><ul><li>Even though forces are equal, they are not balanced because they act on different objects. </li></ul>
9. 10. Action & Reaction <ul><li>What is the action and reaction of a swimmer pushing off the wall? </li></ul><ul><li>As the swimmer pushes on the wall, the wall exerts a force pushing her forward. </li></ul><ul><li>As the swimmer pushes the water out of the way, the water pushes the swimmer back. </li></ul>
10. 11. Action & Reaction <ul><li>What is the action and reaction of the diver? </li></ul>
