6. NEWTON’S LAWS OF MOTION AND APPLICATIONS

7. Objectives: At the end of this lesson the students should be able to: Understand the Laws of Motion; Explain Newton’s Three Laws of Motion; Show examples of situations demonstrating Newton’s Three Laws of Motion.

8. What is Motion? 8 Change with time of the position or orientation of a body. An act, process, or instance of changing place.

9. Born in 1642 An English physicist and mathematician Attended the Trinity College of Cambridge Newton’s Laws of Motion Isaac Newton

10. LAWS OF MOTION

11. Law of Inertia The Law of Inertia states that “an object at rest stays at rest and an object in motion stays in motion in constant velocity, unless acted upon by an unbalanced force.”

12. Law of Acceleration The Law of Acceleration states that “ the acceleration of an object is directly proportional to the force and inversely proportional to the mass of the object.”

13. Acceleration is the measurement of how quickly an object changes speed or velocity. Formula: where, F the force applied on an object in newtons ( N ) m the mass of an object in kilograms ( kg ) a the acceleration of an object in meters per second squared ( m/s 2 )  

14. The applied net force is directly proportional to the acceleration of an object; this is when the mass of an object is constant . The mass of an object is inversely proportional to the acceleration; this is when the force is constant 15

15. Law of Interaction “For every action, there is an equal but opposite reaction”

16. Laws of Motion Law of Intereaction Law of Acceleration Law of Inertia

17. Once more.. State the Three Laws of Motion. Cite some practical examples where the Three Laws of Motion occur. How is force affected by the change of acceleration and mass? Explain what happens to a man riding a car when: The brakes are suddenly applied. The car suddenly moves.

18. Group 1: Law of Inertia Group 2: Law of Acceleration Group 3: Law of Interaction Activity Time! Instructions: Count 1, 2, 3 for your group assignment. Each group have 3mins to prepare and 2mins to show in class an application of each Laws of Motion.

19. Identify the law of motion that is illustrated by the following situations: (Law of Inertia, Law of Interaction, Law of Acceleration) A riffle recoils when fired. A car still moves for a short period even after the brakes have been applied. A follow-through is needed when a golfer hits the ball with a golf club. A rocket lifts off from a space-shuttle system.
