- 1. Newton’s Law of Motion
- 2. Newton’s First Law of Motion <ul><li>Every body continuous in its state of rest, or uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it. </li></ul><ul><li>Inertia </li></ul><ul><li>The tendency of an object to resist any attempt to change its velocity </li></ul><ul><li>Mass </li></ul><ul><li>A measure of the inertia in the body. </li></ul><ul><li>Mass is a scalar quantity and obeys the rules of ordinary arithmetic </li></ul>
- 3. Newton’s Second Law of Motion <ul><li>The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. </li></ul>
- 4. Weight distinguished from mass <ul><li>Weight </li></ul><ul><ul><ul><li>The weight of the body is that force exerted on the body by the pull of gravity. </li></ul></ul></ul><ul><ul><ul><li>The basic relationship of FORCE and MASS is the 2 nd Law of Motion: </li></ul></ul></ul><ul><ul><ul><li>In gravitational case: </li></ul></ul></ul>
- 5. Newton’s Third Law of Motion In every action there is always opposed an equal reaction.
- 6. Important Terms: <ul><li>Tension </li></ul><ul><ul><ul><li>Forces which tend to PULL matter apart along some axis </li></ul></ul></ul><ul><li>Compression </li></ul><ul><ul><ul><li>Forces which tend to PUSH matter apart along some axis </li></ul></ul></ul><ul><li>Friction </li></ul><ul><ul><ul><li>Force that acts to oppose the start or continuance of sliding motion between surfaces </li></ul></ul></ul>
- 7. Free-Body Diagram, FBD <ul><li>Free-body diagram is a pictorial representation often used by engineers to analyze the FORCES acting on the body. And the body is isolated from any effects of the surroundings. </li></ul>
- 8. Sample Problem 1: <ul><li>Draw the free-body diagram of the following: </li></ul>
- 9. Sample Problem 2: <ul><li>Draw the free-body diagram of the figure shown </li></ul>
- 10. Seatwork: Draw the free body diagram of the following:
- 11. Assignment: <ul><li>Draw the free body diagram of the following: </li></ul>
- 12. For next meeting: <ul><li>Define the following: </li></ul><ul><li>Line of action </li></ul><ul><li>Equilibrium </li></ul><ul><li>Conditions of equilibrium </li></ul><ul><li>Static equilibrium </li></ul><ul><li>Dynamic equilibrium </li></ul><ul><li>Questions: </li></ul>
- 13. Reference: <ul><li>Physics for Scientists and Engineers with modern Physics 7 th Edition by Jewett/Serway © 2008 Thompson Learning Inc. </li></ul>
