  1. May The Force Be With You!

  2. Motion:is a change in position, measured by distance and time.

  3. Force • Any push or pull on an object. • Starts, stops, or changes the direction and speed of an object.

  4. Gravity • The Force of attraction between any two objects in the universe.

  5. The force which pulls all objects towards the center of the Earth.

  6. Centripetal The Force that pulls objects toward the center keeping them in a circular motion.

  7. Buoyant Force An upward force exerted by a fluid.

  8. Lift • Drag • Thrust

  9. Friction Friction is a force that causes or stops motion when two surfaces rub against each other.

  10. Types of friction: • Static friction –friction force that acts on objects that are not moving. • Sliding friction–friction force that opposes the direction of motion of an object as it slides over a surface. • Rolling friction -friction force that acts on rolling objects. • Fluid friction – friction force that opposes the motion of an object through a fluid.

  11. Static Friction

  12. Sliding Friction

  13. Fluid Friction

  14. Rolling Friction

  15. Forces occur in pairs • Forces are either: Unbalanced Balanced

  16. Balanced Forces • They are equal in size and opposite in direction. Do not cause a change in motion

  17. Unbalanced Forces • They are not equal and are opposite in direction. Always cause a change in motion

  18. BALANCED FORCES UNBALANCED FORCES

  19. That’s it for today … May the Force be with you!
