  1. Force and Motion Daily Warm-ups

  2. January 28: • Copy the following for Your Notes: • Distance can be defined as the total length of a path that an object travels. • Displacement is not the same as distance. Displacement is the straight line distance and direction between your starting and ending point.

  3. Daily Opener 31-Jan-14 Please write out the question or statement and answers/responses. You want to find out how the different patterns on sneaker soles affects traction on a basketball court. What would be your independent variable? A. sneaker brand B. sneaker sole pattern C. sneaker sole material D. sneaker size

  4. Daily Opener 3-Feb-14 Please write out the question or statement and answers/responses. To find an object’s displacement, you must know the distance it has traveled, as well as it’s ____. A. speed B. route C. motion D. direction

  5. Daily Opener 4-Feb-14 Show the formula used to solve speed for each line. This graph shows the distance traveled by four objects over a period of 5 seconds. Look closely at the graph. Which line on the graph represents the object with the greatest average speed? A. 4 B. 3 C. 2 D. 1

  6. Directions: 1- Do NOT mess with the items at stations. You will not participate if you can not follow this request. 2- Answer the question and state the reason for your answer. Daily Opener 5-Feb-14 Which line on the graph represents an object that is not moving? A. 1 C. 3 B. 2 D. 4

  7. Daily Opener 6-Feb-6 Please write out the question or statement and show the formula with the numbers plugged in to the formula to solve the equation. A bird flies for 2 hours at a constant speed of 34.2 km/h. How far does it fly? A 68.4 km B 41.1 km C 17.1 km D 3.5 km

  8. Daily Opener 7-Feb-14 Please write out the question or statement and answers/responses. 22) When you know both the speed and direction of an object, you know the ______. A. velocity of the object B. distance the object has traveled C. average speed of the object D. acceleration of the object

  9. Daily Opener 10-Feb-14 Please write out the question or statement and answers/responses. Sir Isaac Newton changed our understanding of the world and the universe when he came up with his three laws of __________. A. alchemy B. acceleration C. gravity D. motion

  10. Daily Opener 11-Feb-14 Please write out the question or statement and answers/responses. A student has a set of masses to use in an experiment about force. Which mass has the greatest inertia? A. 1 g mass B. 5 g mass C. 25 g mass D. 100 g mass

  11. Daily Opener 12-Feb-14 Please write out the question or statement and answers/responses. A book is sliding along a desktop. Because the book is in motion, you know that forces acting on the book are _______. A. balanced B. Unbalanced C. in one direction only D. pushing upward and downward only

  12. Daily Opener 13-Feb-14 Please write out the question or statement and answers/responses. You are pushing on the left side of a box with a force of 18 N. Your friend is pushing on the right side of the box with a force of 16 N. Which statement is true? A. The net force is up with a strength of 2 N. B. The net force is to the right with a strength of 2 N. C. The net force is down with a strength of 2N. D. The net force is to the left with a strength of 2 N.

  13. Please write out the question or statement and answers/responses. Daily Opener 14–Feb–14 26 N 38 N Which direction will this box move and with how much force? A) Left with 64 N of force. B) Left with 12 N of force. C) Right with 12 N of force. D) The forces are balanced and the box will not move.

  14. Daily Opener 7-Oct-13 Please write out the question or statement and answers/responses. 30) A student has a set of masses to use in an experiment about force. Which mass requires the least force to overcome static friction? A. 100-g mass B. 105-g mass C. 125-g mass D. 130-g mass
