Unit 3 Summary

Unit 3 was focused mainly on these three equations:

d = ½ at^2 + VoT

V = Vo + at

V^2 = Vo^2 + 2ad

These equations were basically used to help us figure out the values of unknown variables such as figuring out the height of a cliff when given the time it takes to fall down and the acceleration of gravity.

Additionally to that, we learned the relationships between graphs displaying data like position versus time, velocity versus time, and acceleration versus time. These graphs helped us apply our equations to real life situations such as balls falling, cars increasing speed, etc.

Overall, Unit 3 was very interesting and challenging because of a lot of technical things such as making mathematical errors in calculations. The most challenging part for me was keeping track of which direction the acceleration was working in. For example, if a ball was thrown up, gravity is accelerating it down but the value of gravity can change between 9.8 m/s^2 to -9.8 m/s^2 depending on whether or not you wanted the cliff to be x meters high or –x meters high.
