  3. PS1B: Types of Forces I can: • Describe what causes friction • Describe the forces acting on an object: • normal force • frictional forces • Weight (mg) • Gravity • effort force • resistance forces • Describe the relationship between force, mass and acceleration

  4. Please select a Team. • Team 1 • Team 2 • Team 3 • Team 4 • Team 5 • Team 6

  5. The normal force vector arrow should 32 • Point left • Point right • Point up • Point down 0 0 0 0 F Normal 0 F weight 10 Countdown

  6. The normal force vector arrow should 32 • Be equal in size to the weight • Be larger than weight • Be smaller than weight 0 0 0 F Normal 0 F weight 10 Countdown

  7. The normal force is what? 32 • The force from the weight pushing down. • The force from the mass of the object • The force from the ground pushing up so the object does NOT fall. 0 0 0 F Normal 0 F weight 10 Countdown

  8. If you increase the mass of the object then what will happen? 32 • Weight vector arrow will increase • Normal force vector arrow will increase • Both the normal force & weight vector arrow will increase • Neither the normal force or weight vector arrow will increase 0 0 0 0 F Normal 0 F weight 10 Countdown

  9. If you increase the mass of the object why does the weight increase There is more weight to get pushed down It is heavier There is more normal force There are more atoms that get pushed down by gravity 0 0 0 0 32 F Normal 0 F weight 10 Countdown

  10. If the object is just sitting there (doing nothing) is there friction? Yes No 0 0 32 F Normal 0 F weight 10 Countdown

  11. The box is pushed to the right by a person, but not hard enough to move it. What is the effort force? 32 • The box • Gravity • Normal force • Friction • The person 0 0 0 0 0 F Normal F Effort 0 F weight 10 Countdown

  12. The box is pushed to the right, but not hard enough to move it. What direction will the resistance force point? 32 • Left • Right • Up • Down 0 0 0 0 F Normal F Effort 0 F weight 10 Countdown

  13. The box is pushed to the right, but not hard enough to move it. What is the resistance force? 32 • Mass • Weight • Mass & Weight • Gravity • Friction 0 0 0 0 0 F Normal F Effort F Friction 0 F weight 10 Countdown

  14. The box is pushed to the right, but not hard enough to move it. How big should the friction (resistance) force be? 32 • Bigger than the effort force • Smaller than the effort force • The same size as the effort force 0 0 0 F Normal F Effort F Friction 0 F weight 10 Countdown

  15. The box is pushed to the right with more force, but not hard enough to move it. What changes in the force vectors? 32 • The effort force will be bigger • The resistance force will be bigger • The resistance & effort force will be bigger 0 0 0 F Normal F Effort F Friction 0 F weight 10 Countdown

  16. Team Scores

  17. Jeopardy: What percentage of your current points would you like to wager on the next question? • 0% • 25% • 50% • 75% • 100% 10 Countdown

  18. The box is pushed to the right with more force, but not hard enough to move it. Which will be larger/stronger? 32 • The effort force will be larger/stronger • The resistance force will be stronger • The resistance & effort force will be will be the same size (just stronger for both) 0 0 0 F Normal F Effort F Friction 0 F weight 10 Countdown

  19. Team Scores

  20. The box is pushed to the right with more force until it moves. What changes in the force vectors? 32 • The effort force will be stronger than the resistance • The resistance force will be stronger than the effort force • Gravity will be bigger • The normal force will be bigger 0 0 0 0 F Normal F Effort F Friction 0 F weight 10 Countdown

  21. The box is pushed to the right with more force until it moves. It is then let go so it coasts. What happens? 32 • The effort force will get weaker/smaller • The friction force will get weaker/smaller • The effort force will disappear 0 0 0 F Normal F Effort F Friction 0 F weight 10 Countdown

  22. The box’s mass is increased. What happens to the minimum force needed to move the box? 32 • Increases • Decreases • Stays the same 0 0 0 F Normal F Effort F Friction 0 F weight 10 Countdown

  23. The box’s mass is increased. Why does it take more effort force to move the box? There is more friction There is more gravity There is more weight There is more normal force 0 0 0 0 32 F Normal F Effort F Friction 0 F weight 10 Countdown

  24. We switch the planet to Jupiter. Which will have more friction? Object on Jupiter Object on Earth Same amount on Earth & Jupiter 0 0 0 32 F Normal F Effort F Friction 0 F weight 10 Countdown

  25. The object is moved to Jupiter. Why will Jupiter have more friction? More mass on Jupiter so it grips the ground more More gravity on Jupiter so it grips the ground more More vapors/gases on Jupiter so it gets pushed down more 0 0 0 32 F Normal F Effort F Friction 0 F weight 10 Countdown

  26. The object is pushed on a wood floor and on carpet. Which will have more ground friction Wood floor Carpet Same amount 0 0 0 32 F Normal F Effort F Friction 0 F weight 10 Countdown

  27. The object is pushed on a wood floor and on carpet. Which will be easier to start to move..take less effort force? On a wood floor On a carpet Same amount 0 0 0 32 F Normal F Effort F Friction 0 F weight 10 Countdown

  28. Team Scores

  29. Jeopardy: What percentage of your current points would you like to wager on the next question? • 0% • 25% • 50% • 75% • 100% 10 Countdown

  30. What causes friction? How well the object grips the ground Gravity Mass of the object Material the object is made out of Material the ground is made out of Pushing an object All of the above 0 0 0 0 0 0 0 32 F Normal F Effort F Friction 0 F weight 10 Countdown

  34. PS1B: Types of Forces I can: • Describe what causes friction • Describe the forces acting on an object: • normal force • frictional forces • Weight (mg) • Gravity • effort force • resistance forces • Describe the relationship between force, mass and acceleration

  35. Rate your ability on the following learning target:Describe what causes friction • F: I don’t understand how.I make lots of mistakes. • D: I have a below average understanding. I can do it, but make many mistakes. • C: I have an average understanding.I can do some of it, but I make several mistakes. • B: I have an above average understanding. I could do it myself without help, but I sometimes make a few mistakes. • A: Excellent understanding. I could teach how to do this to someone else. I rarely make mistakes. 0 0 0 0 0
