3 SCIENCE 8 Graphing Acceleration M.10 Name: Date: Homeroom: Motion We like to MOVE IT, MOVE IT! OBJECTIVES: By the end of class, students will be able to SWBAT understand and explain a velocity vs. time graph. DO NOW 1. What is the car s motion relative to the starting point at time = 6 minutes? A. at rest B. motion along 600 m C. moving toward the starting point D. moving away from the starting point 2. What is the total distance traveled by the car after 10 minutes? A. 600 meters B. 1,200 meters C. 2,000 meters D. 3,600 meters CONCEPT CHECK Two types of plate boundaries are divergent and convergent. A. Copy arrows from the sidebar into the two blank boxes to show how the convection currents in the mantle would move at a divergent plate boundary. B. Copy arrows from the sidebar into the two blank boxes to show how the convection currents in the mantle would move at a convergent plate boundary. Copy the arrows exactly as given. Write only one arrow in each blank box. 3

4 You may use each arrow more than once. 4

5 YOU REVIEW CHECK YO SELF: Demonstrate your understanding Position vs. Time graphs, by explaining the motion in each graph below. BONUS CHECK: Can you calculate the average velocity for each motion? #1 #2 #3 #4 5

6 DRAW ME A STORY! 1. Jo vanna and Ja Laiya were taking part in potato sack races at this year s field day. The girls started the race slowly, but sped up at a constant rate. As they approached the turn around point, the girls slowed down so they wouldn t fall, but quickly sped up at a constant rate until getting to the finish line. What does their motion look like if we display their change in position as a linear motion map? What does their motion look like if we compare their change in position over time? What does their motion look like if we compare their change in velocity over time? How does their velocity become negative? 6

MATH + REAL WORLD = SCIENCE CLASS PRACTICE There once was a speedy hare who bragged about how fast he could run. Tired of hearing him boast, Slow and Steady, the tortoise, challenged him to a race.

7 MATH + REAL WORLD = SCIENCE CLASS PRACTICE There once was a speedy hare who bragged about how fast he could run. Tired of hearing him boast, Slow and Steady, the tortoise, challenged him to a race. All the animals in the forest gathered to watch. Hare ran 8 meters down the road in four minutes and then paused to rest. He looked back at Slow and Steady and cried out, "How do you expect to win this race when you are walking along at your slow, slow pace? You ve only gone 4 meters! " Hare stretched himself out alongside the road and fell asleep, thinking, "There is plenty of time to relax." Slow and Steady walked and walked. He never, ever stopped until he came to the finish line another 8 minutes later. The animals who were watching cheered so loudly for Tortoise as he crossed the finish line, they woke up Hare. Hare stretched and yawned and sprinted, reaching the line in 2 minutes flat! But it was too late, the race was already over. After that, Hare always reminded himself, "Don't brag about your lightning pace, for Slow and Steady won the race!" DRAW THE STORIES! 7

8 Velocity v Time Graphs Note 1: This type of graph displays how an object s velocity has changed with time. Note 2: The steeper the slope, the faster the speed is changing, the greater the acceleration. Note 3: A horizontal means the object is not changing speed or direction it is AT CONSTANT VELOCITY. Note 4: A downward slope means the object has a NEGATIVE ACCELERATION. EXAMPLE 1: Graphing 8

9 Example 2: Interpreting The graph below shows how the speed of a bus changes during part of a journey. Explain what is occurring during each of the segments with words, and then with calculations.

13 Science 8 Name: SKILL SNAPSHOT Date: Homeroom: M.10: Graphing Acceleration Quick Notes: Like A Scholar? Directions: Read and ANNOTATE the information before you solve the problem. Yes No Redo? Yes No Two cars, A and B, are moving as illustrated in the figure. The numbers represent readings of a clock in minutes. At each clock reading the position occupied by each car is represented by a large black dot. At clock time 1 car A occupies the position marked 1, and ball car occupies the position marked 1, etc. The arrows indicate the direction of motion of both car. Each line is 1 mile in total length. 1. Which object(s) is(are) accelerating? A. both A and B B. neither A nor B C. only A D. only B 2. The motion of which object(s) would be represented by a horizontal line on a velocity versus time plot? A. only A B. only B C. both A and B D. neither A nor B 3. Consider the graph. Select the three statements about the object whose motion is represented by this graph. A. moving with a positive acceleration. B. moving with a constant acceleration. C. changing directions. D. moving in the positive direction. E. moving with a constant velocity. F. slowing down. G. speeding up. 13

4. A snowboarder begins his run from rest (point 1) on top of a hill. He moves straight down the slope, speeding up until he reaches the bottom of the hill (point 4) and the ground levels off.

14 4. A snowboarder begins his run from rest (point 1) on top of a hill. He moves straight down the slope, speeding up until he reaches the bottom of the hill (point 4) and the ground levels off. The snowboarder continues to move horizontally across the level ground and eventually comes to a stop (point 5). Which graph best represents the speed of the snow boarder as he moves from point 4 to point 5? A. B. C. D. CONCEPT CHECK The diagram represents a convection current in Earth s mantle. Descriptions of the events at each of the positions are shown, 5. Write the number that accurately describes the event occurring at that position in the convection current. 14
