Summary: To understand acceleration we need to know some definitions and defining features. For example to really begin we must know about velocity. Velocity is distance over time. Velocity is also a vector which means it cares about the direction that the object is moving in. For acceleration we have velocity over time. When graphing it you must find the velocity of the object then you do a velocity over time. With acceleration we want to see how much it moved from the initial value lets say you started at zero then your initial value is zero then you subtract that by the final velocity it reaches. Then after that you must divide that number by how ever many seconds it took to get to the final value. If lets say you are doing this in units or cm or anything different then the value of the acceleration rate then you must divide it by that number for example if you need to turn it into meter instead of cm then you would divide by 100 because there are 100 cm in a meter. One you have that number you have your acceleration rate.

S&EP: Conducting Investigation: 

Over the course of our time understanding acceleration and deceleration we did a lab to be able to formalize our understanding these topics. When you see it in front of you it is easier to put numbers to actions. An obvious observation is whenever we put the car higher on the track it would move faster. It does time because the higher the slope the more of a gravitational pull it has on the car we used. We saw this in two senses. One where we stacked only a few books to create our track's slope. You can see the that car moved slower this time then when we had the higher slope of having it come off the side of our table. To understand deceleration we put it a little higher up but we didn't start counting until it hit the track the the floor were flush. You could notice at this time without gravity pulling on it as much the less and less it would reach each second.

XCC: Cause and Effect: 

Motion is all about cause and effect. You can basically assume if you are the throw a ball it would move and it would eventually hit the floor. We know this because we know that first of all throwing it will make it go into motion and gravity will pull it down. That is why things tend to not stay at a constant speed especially if they are not on an even terrain.  If you roll a wheel down a hill it will speed up on the slope and then  come to a stop but if you roll a wheel on even ground it will not be changed by gravity and will be at more of a consistent rate. In conclusion gravity causes a change in motion.
