  1. Computer Simulation Review Ungraded

  2. Enter #1 30 • Enter answer text... 0 Non-Response Grid 0 10 Countdown

  3. PS1C: Balanced & Unbalanced Forces • Given a description of motion be able to identify the net forces acting on the object • Speeding up • Slowing down • Constant speed • Not moving • Predict the resulting motion of an object when a new force acts on it.

  4. Rate your ability on the following learning target: 30 • 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 0 10 Countdown

  5. Applying a balanced net force to a nonmoving object

  6. The cart is NOT moving. The person then pulls with a balanced net force to the left. This means what? 30 • The effort force will equal the resistance force • The effort force will be bigger than the resistance force • The effort force will be smaller than the resistance force 0 0 0 Resistance Effort Friction 0 10 Countdown

  7. The cart is NOT moving. The person then pulls with a balanced net force to the left. This means the cart will 30 • Begin to move, but very slowly • Begin to move, but more quickly • Not move 0 0 0 Resistance Effort Friction 0 10 Countdown

  8. Applying an Unbalanced Net Force to a nonmoving object

  9. The cart is NOT moving. The person then pulls with an unbalanced net force to the left. This means what? 30 • The effort force will equal the resistance force • The effort force will be bigger than the resistance force • The effort force will be smaller than the resistance force 0 0 0 Resistance Effort Friction 0 10 Countdown

  10. The cart is NOT moving. The person then pulls with an unbalanced net force to the left. This means the cart will 30 • Positively accelerate (speed up) • Negatively accelerate (slow down) • Not move 0 0 0 Resistance Effort Friction 0 10 Countdown

  11. Applying a Balanced Net Force to an Object that is speeding up

  12. Another person is added who pulls to the right with a balanced net force. This other person’s forces on the cart would look like what? 30 • His effort force would be equal to resistance • His effort force would be bigger than resistance • His effort force would be smaller than resistance 0 0 0 Resistance Effort +25N -25N (25N) Resistance Effort (50N) Friction 0 10 Countdown

  13. Another person is added who pulls to the right with a balanced net force. This other person’s forces would cause the speed of the car to do what? 30 • Has no effect. It will continue to speed up to the left. • The cart will slow down and go a constant speed. • The cart will slow down to a stop 0 0 0 (25N) Effort Resistance Resistance Effort (50N) +25N -25N Friction 0 10 Countdown

  14. Why will the cart not be affected by the new balanced net force that is added? 30 • Because the overall net force is unbalanced still to the left • Because the overall net force is now 0 0 (25N) Effort Resistance Resistance Effort (50N) +25N -25N Friction 0 10 Countdown

  15. Applying an Unbalanced Net Force to an Object that is speeding up

  16. Another person is added who pulls to the right with an unbalanced net force. This other person’s forces on the cart would look like what? 30 • His effort force would be equal to resistance • His effort force would be bigger than the resistance • His effort force would be smaller than resistance 0 0 0 Resistance Effort -25N +50N (25N) Resistance Effort (50N) Friction 0 10 Countdown

  17. Another person is added who pulls to the right with a unbalanced net force. This other person’s forces would cause the speed of the car to do what? 30 • Has no effect. It will continue to speed up to the left. • The cart will slow down and then go a constant speed. • The cart will slow down to a stop 0 0 0 (50N TOTAL) (25N) Effort Resistance Resistance Effort (50N) -25N +50N Friction 0 10 Countdown

  18. Applying a lot of Unbalanced Net Force to an Object that is speeding up

  19. Another person is added who pulls to the right with an unbalanced net force. This other person’s forces on the cart would look like what? 30 • His effort force would be equal to resistance • His effort force would be bigger than the resistance • His effort force would be smaller than resistance 0 0 0 Resistance Effort -25N +200 (25N) Resistance Effort (50N) Friction 0 10 Countdown

  20. Another person is added who pulls to the right with a unbalanced net force. This other person’s forces would cause the speed of the car to do what? 30 • Has no effect. It will continue to speed up to the left. • The cart will slow down and then go a constant speed. • The cart will slow down to a stop 0 0 0 (200N TOTAL) (25N) Effort Resistance Resistance Effort (50N) -25N +200N Friction 0 10 Countdown

  21. Applying a Balanced Net Force to an Object that is going a constant speed

  22. Another person is added who pulls to the right with a balanced net force. This other person’s forces on the cart would look like what? 30 • His effort force would be equal to resistance • His effort force would be bigger than the resistance • His effort force would be smaller than resistance 0 0 0 Resistance Effort -25N +25 (50N) Resistance Effort (50N) Friction 0 10 Countdown

  23. Another person is added who pulls to the right with a unbalanced net force. This other person’s forces would cause the speed of the car to do what? 30 • Has no effect. It will continue to go a constant speed • The cart will slow down and then go a constant speed. • The cart will slow down to a stop 0 0 0 (0N TOTAL) (50N) Effort Resistance Resistance Effort (50N) -25N +25N Friction 0 10 Countdown

  24. Applying an Unbalanced Net Force to an Object that is going a constant speed

  26. Another person is added who pulls to the right with a unbalanced net force. This other person’s forces would cause the speed of the car to do what? 30 • Has no effect. It will continue to go a constant speed • The cart will slow down and then go a constant speed. • The cart will slow down to a stop 0 0 0 (0N TOTAL) (50N) Effort Resistance Resistance Effort (50N) -25N +200N Friction 0 10 Countdown
