Science Class on the 17th of Nov. 2009

Today in class we did more laptop work. The laptop work included:

• Class notes on google docs. Ms. D. says you may replace this for handwritten notes if you want to. You don't have to if you don't want to. The class notes look like this:
• Another subject we covered in class was the definition words that have to do with motion. Hear they are copied off google docs:
• Motion: the state in which an object's distance from its reference point is changing. Motion is determined by a reference point.
• Reference Point: An object or place that is used to compare if something is moving or not. The Reference Point should not be moving.
• Instantaneous speed: The speed an object is moving when given a certain amount of time.
• Velocity: The speed of an object in a certain direction. ex. 158km/13hrs. North
• Speed: How fast something travels per unit of time. To find out the speed you must divide distance by the time given. (s=d/t) kmph, m
• Average Speed: Two points on graph. Total distance divided by time is how you find the average speed. The points are start to end point. (not always accurate)
• We also covered math problems using formula, plug, and chug. Unit of distance/secs, km, or meters
• The homework for todays class was to look at the bog which you are doing if you see this. The other assignment are to do the speed math sheet problems.
• The next scribe is Laura.
