D t graph cornell notes
- 1. Agenda: Motion Graphs Cornell Notes Bellwork: James ran 400 kilometers in 24 hours. Calculate his speed. Kelly skipped 30 meters in 3.5 minutes. Calculate her speed.
- 2. What are the differences between Speed and Velocity?
- 3. How do we calculate Speed, Distance and Time? Speed = Distance Time Distance = Speed ´ time Time = Distance Speed
- 4. What are DISTANCE-TIME GRAPHS? Distance-time graphs can be used to describe journeys. distance on the vertical (y) axis time on the horizontal (x) axis.
- 6. What does a d-t graph look like with no movement? Flat
- 7. How can you tell an object is moving fast? Line slopes up at a steep angle
- 8. When the object goes back to the starting point, what does the graph look like? Slopes down
- 9. What does a d-t graph look like for acceleration (speeding up)? curved
- 10. EXAMPLES 1. The following graph describes the journey of a snail. a. Describe the motion of the snail. b. What is the speed of the snail during each part of the journey? MEP Y8 Practice Book B18.4 Example 1 The graph shows how far a child is from home. Distance (m) 200 400 0 600 800 1000 0 20 40 60 80 100 120 140 160 180 200 Time (seconds)
