Unit 3: Continued

We learned more in depth how to analyze various graphs, the relationship between acceleration and gravity, and we reviewed how to use the three equations DAT, VAT and VAD. In this picture we were testing whether which ball would fall first and we found out that they would reach the ground at the same time because they are accelerating at the same place. Even though the balls had different masses and volumes, they still hit the floor at the same time.

We also learned the velocity of an object after you throw it up would be fast, then slow, then it will stop at its peak, then it will come back down slowly, and then speed up again all before you catch it again. If you catch the object at the same place you threw it, then the velocity would be exactly the same except the opposite. On earth, the acceleration is always 9.8 m/s^2 or 10 m/s^2 because that is the pull of gravity.
