Acceleration


Today, we learned the basics of Acceleration. This included many confusing equations, like d=1/2at^2+Vot, V= Vo+at, and V^2=Vo^2+2ad. One that was more easily understandable is acceleration equals the change is velocity over change in time (The final velocity minus the original velocity over the final time minus the original time) .
If I were to apply this equation: Say that a car sped up from 1,000 meters per second (around 37 mph) to 2,000 meters per second in twenty seconds, and it took the car ten seconds to get from zero meters per second to 1,000, I could find the acceleration.
2,000 meters per second minus 1,000 meters per second is 1,000
Twenty seconds minus ten seconds is ten seconds
1,000 meters per second divided by ten seconds equals 100 meters/seconds^2
100 meters/seconds^2 is the acceleration :)
