  1. Balanced and Unbalanced Forces

  2. Essential Question: How can motion be described? I CAN STATEMENT: • I CAN identify the difference between balancedand unbalancedforces.

  3. What is a Force? ¿Qué es una fuerza?

  4. Force: A push or a pull that acts on an object. Fuerza: Es el empuje o la atracción que actúa sobre un objeto. A force is defined as a _________ or ___________ on an object. Forces are measured in _____________ (N).

  5. Balanced Forces & Unbalanced Forces

  6. First, • you will watch a video on: Balanced & Unbalanced Forces. Then, • You will answer questions about the video after.

  7. Are the forces balanced or unbalanced? (arrows are same size, & in opposite directions)

  8. Are the forces balanced or unbalanced? (More force to the right, & in opposite directions)

  9. Are the forces the SAME or DIFFERENT SIZES? • The sizes are ________.

  10. Are the forces in the SAME or OPPOSITE DIRECTIONS? 2. The direction is ________.

  11. Are the forces balanced or unbalanced? 3. The forces are __________.

  12. What is happening in this image?!? • What is the total amount of force (Net Force) to the left?

  13. Are the forces in the SAME or OPPOSITE DIRECTIONS? 2. The direction is ________.

  14. Are the forces balanced or unbalanced? 3. The forces are __________.

  15. There are always FORCES at work!

  16. The forces are _______________.

  17. The forces are _______________.

  18. The forces are _______________.

  19. The forces are _______________.

  20. The forces are _______________. The car slow down.

  21. The forces are _______________.

  22. The forces are _______________.

  23. Balanced forces Examples At rest At rest At rest At a constant speed and same direction At a constant speed and same direction

  24. Balanced forces _______________. A: cAUSE A CHANGE IN MOTION B: dO NOT CAUSE A CHANGE I N MOTION C: cAUSES ACCELERATION

  25. Balanced forces _______________. A: cAUSE A CHANGE IN MOTION B: dO NOT CAUSE A CHANGE I N MOTION C: cAUSES ACCELERATION

  26. UNBalanced forces Examples 35 N 40 N stronger 20N 10N Moves Left Changing directions

  27. unBalanced forces _______________. A: cAUSE A CHANGE IN MOTION (acceleration) B: dO NOT CAUSE A CHANGE I N MOTION

  28. unBalanced forces _______________. A: cAUSE A CHANGE IN MOTION (acceleration) B: dO NOT CAUSE A CHANGE I N MOTION
