Physics lesson2 force&motion

  1. 1. Lesson 1March 9, 2012
  2. 2. Today’s Outline FORCE AND MOTION:  Common Terms  Force  Newton’s First Law of Motion
  3. 3. Common Terms Mechanics – The study of motion of objects Kinematics – The science of describing motion (through words, charts, graphs, diagrams, equati ons etc.) For this class, we will be looking at Free-Body Diagrams
  4. 4.  Speed – Describes how fast an object is moving Speed = Distance time
  5. 5. Velocity Speed of an object in a certain direction v = velocity (meters / second) d = distance (meters) t = time (seconds) d V= t
  6. 6. Acceleration is how quickly velocitychanges over a certain time. change in Acceleration = velocity time (v2 – v1 ) _______ Acceleration = _ Time V1 = beginning velocity V2 = ending velocity
  7. 7. Scalar Quantity:A measurement that can be fully described by a magnitude (a numerical value) alone. Example: Speed, distance, timeVector Quantity:A measurement that needs a magnitude as well as a direction for its description. Example: Velocity, Force
  8. 8. Definition, Categories, Types, and Visual Representation
  9. 9. FORCE A force is a push or pull upon an object that occurs because when that object interacts with another object Forces ONLY exist when there is interaction. Keep in mind that objects includes anything and everything, including the Earth
  10. 10.  Measured in Newton One Newton is the amount of force required to give an object of 1Kg an acceleration of 1 m/s². A force is a vector quantity (has to have a direction)
  11. 11. Categories of ForceTwo major categories:1. Contact Force: The types of forces that occur when two objects are said to be in physical contact with each other.2. Action-at-a-Distance Force: Forces that result even when two interacting objects are not in physical contact with each other.
  12. 12. Contact Forces Frictional Force Tension Force Normal Force Air Resistance Force Applied Force Spring Force
