Acceleration can be seen everywhere, escpecially in this day and age where everything needs to accelerate to be transported. In my words acceleration is starting momentum seen with speed and velocity. But according to websters dictionary it means is the rate of change in velocity as a fuction of time. It is a vector
Hypothises-The time it takes for the pendulem to swing back and forth is shortened when the string is shortened.
Materials-String, weight, stopwatch
Methodology-We took the string, tied it to the weight, swang it back and forth ten times, timed how long this took, and recorded our data. We did this 7 times. Everytime we did this we shortended the string just a little bit. Each time we got a differant result.
Conclusion-the lab proved to be a sucesses! We recorded our data on a graph and we discovered
as the string gets shorter, the time on the stopwatch gets longer.
