Unit 3!
Unit 3 focuses mainly on acceleration. But because acceleration is affected by velocity, distance, and time, unit 3 also focuses on that as well. On day 2 of this unit, we learned more about how an object's movement looks on a position vs. time graph, velocity vs. time graph, and acceleration vs. time graph. Through our two labs, we learned about Galileo, his idea of uniform acceleration, and how objects in free fall look on the three graphs. We also reviewed our different equations and how to use them to solve problem one step and multiple step problems.
I used the picture above to represent acceleration because hitting a volleyball demonstrates changes in velocity. When you throw the ball up in the air, it accelerates quickly as you release it. But as it continues to to go up, gravity starts to slow down its acceleration. Then when you hit the ball, the impact causes the acceleration to change once again!
I like how you used playing volleyball and throwing it in the air as an example even though that was sort of what we did in class because everyone was playing with the volleyballs instead. haha! You also explained in a brief way everything that we learned today in class :)
ReplyDeleteI like how I was able to see this picture being taken in real life. Seems like you guys had a lot of fun during the break :) You also described what we did in class clearly.
ReplyDeleteI really like your picture and how you connected it with gravity and acceleration. It's really like the lesson we learned in class. I also liked the great detail you used in explaining the lesson!
