This document provides an overview of Isaac Newton's three laws of motion. It introduces Newton and his accomplishments, then explains each of the three laws: 1) Law of Inertia - an object at rest stays at rest and an object in motion stays in motion unless acted on by an outside force, 2) Law of Acceleration - an object accelerates only if a net force acts upon it, and 3) Law of Interaction - for every action there is an equal and opposite reaction. Examples are given to illustrate each law and problem solving techniques are presented.

2. LEARNING OBJECTIVES
 Get to know about Isaac Newton.
 State and explain Newton’s Law of Motion.
 Apply the laws of Newton to simple situations.

3. LESSON PROPER
 Definition of Force and Motion (Review)
 Isaac Newton’s Quick Biography
 Newton’s Laws of Motion
 Problem Solving Skills

4. FORCE
 It is any interaction which
tends to change the motion
of an object.

5. MOTION
 One of the most common physical
phenomena.
 A change in position of an object
with respect has a fixed reference
point.
 It is a relative.

6. ISAAC
NEWTON
• English physicist, mathematician, and natural
philosopher.
• One of the foremost scientific intellects of all
time.
• His works are Universal Law of Gravitation
and the Law of Motion.
• He invented calculus and reorganized the
study of physical phenomena.
• His published works are Principia (1687) and
Optiks (1704).

8. NEWTON’S LAW OF MOTION
 These are three physical laws that together laid the
foundation for classical mechanics. They describe the
relationship between a body and the forces acting
upon it, and its motion in response to said forces.

9. LAW OF INERTIA
 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 outside force.

10. INERTIA
 It is the resistance of any physical object to any
change in its state of motion, including changes to its
speed and direction. It is the tendency of objects to
keep moving in a straight line at constant velocity.

11. LAW OF ACCELERATION
 An object will only accelerate if there is a net
or unbalanced force acting upon it.
 The presence of an unbalanced force will
accelerate an object changing its speed or
its direction or vice-versa.

12. CALCULATION FOR THE 2ND LAW
 When you multiply a kilogram (mass unit) times a meter per second
squared (acceleration unit) you get a kilogram-meter per second
squared.
 So a unit for force is actually the kilogram-meter per second squared.
However, no one really says that. The unit for force is named after
Isaac Newton, and it is called the 'Newton', abbreviated 'N'.
1 N = 1 kg-m/s2
Equation: F = MA

13. EXAMPLE ABOUT ACCELERATION
 An object has a mass of 11.87 kg and an acceleration
of 11.11 m/s/s. What is the force on the object?
 Answer: 131.87 N

14. LAW OF INTERACTION
 For every action, there is an equal and
opposite reaction.

15. TEST YOURSELF
1. If a person is standing on the floor of a bus at rest, and the bus
suddenly starts to move forward, the person is “thrown” backward.
2. A tennis player applies a contact force to ball with her racket,
accelerating and directing the ball toward the open court.
3. Many people are familiar with the fact that a rifle recoils when fired.

16. PROBLEM SOLVING SKILLS
o An object with a mass of 17.21 kg experiences a force
of 13.44 N. What is the acceleration of the object?
Note: A = F/M
o An object with a force of 17.93 N on it is accelerating
at 12.85 m/s/s. What is the mass of the object?
Note: M = F/A
