1. + Physics: Motion

2. + What does one- dimensional motion look like?

3. + What does two - dimensional motion look like?

4. + What kind of motion?

5. + Describing Motion Where are you??

6. + Position Reference Point – a starting point used to describe the location or the position of an object Distance – d – the total length between two point or the total length travelled Position – an object’s distance and direction from a reference point

7. + Where Are We Going?

8. + Position and Direction Number lines or coordinate systems are used to specify position Objects can move in a positive and negative direction North and East – Positive direction South and West – Negative direction

9. + Why is it important to include the plus and minus signs in the position? Reference Point Describe how the rhinoceros moved?

10. + Distance and Displacement Motion is the process of changing position Two ways of describing motion are distance and displacement Displacement is the straight-line distance, or the difference between the initial position and the final position of an object

11. + Measuring Distance and Displacement Distance moved is… 27.4 m Displacement is … 27.4 m [toward first base]

12. + Measuring Distance and Displacement Distance moved is… 54.8 m Displacement is … 38.7 m [toward second base]

13. + Measuring Distance and Displacement Distance moved is… 109.6 m Displacement is … 0 m Displacement is zero because the starting position and the final position are the same.

14. + Scalar Quantities and Vector Quantities Distance and displacement are examples of two types of quantities. Distance is a scalar quantity. Scalar quantity that has only magnitude or size. It is represented by number and units examples: distance, time and temperature A vector is a quantity that has both magnitude and direction. You must include units. Examples: displacement and position

15. + Representing Vectors Arrows are often used to represent vectors. The length of the arrow represents the size and magnitude or motion and the arrow point represents the direction of motion.

16. + Resultant Vector The sum of vectors is called a resultant vector

17. + Displacement Where means “change in” means change in position is position in meters, m represents the final position in meters, m represents the initial position in meters, m

19. + Determining the Time Interval Measured in minutes, hours or seconds What is the time interval?

20. + Activity 5- 1B

21. + Uniform Motion Uniform motion is motion in which the object’s displacement is equal form each time interval

22. + Graphing Uniform Motion What would we graph?? Time and position What would be on the x-axis? Which is the independent variable? Time (seconds) What would be on the y-axis? Which is the dependent variable? Position (cm[right])

23. +

24. + What do slopes mean? Positive slope indicates movement in a positive direction

25. + What do slopes mean? Negative slope indicates movement in a negative direction

26. + What do slopes mean? Zero slope indicates no movement or no change in position
