My picture relates to what we learned in unit 2 because we learned about motion. When people snowboard or ski they are in motion. Going down the slope their velocity or average speed changes as well as their distance and displacement.
Snowboarders and skiers accelerate as they move down the mountains.
Acceleration- a change in velocity per unit of time, any time you change your velocity . You can find the acceleration of a moving object by using the formula: A= V/ T
Snowboarders and skiers move quickly down mountains, sometimes skiers are faster some times snowboarders are faster. You can figure out the speed and position of skiers and snowboarders at different times by using graphing and equations.
The slope of a position vs. time graph is velocity. Position vs. time graph tell you where you are (position.)
The slope of a velocity vs. time graph is acceleration. This type of graph tells you velocity.
This information could be helpful when you need to know where a skier or a snowboarder was at a certain time. If the snowboarder has a velocity of 30 mph and the skier has a velocity of 35 mph then you can conclude that the skier is quicker. On a graph the skiers slope will be steeper.
The area under the curve of a velocity vs. time graph is distance traveled (displacement). If you look at a velocity vs. time graph you can figure out the displacement of a moving object without using an equation.
Your connection with snowboard and velocity is really neat. It also was a good review for the test for me so thank you!
ReplyDeleteI agree with what Devon said. This was a very good review for the test. You summed up the main ideas we learned with a concise statement... it wasn't too confusing. Good job!
ReplyDeleteGood job Candace I like your whole snowboarding slope idea too. It was a cool way at looking at kinematics and you covered pretty much everything
ReplyDeleteNice picture! You did a good job on defining a position vs. time graph and a velocity vs. time graph. You had a lot of information on unit 2. Great job!!
