This week, we have explored kinematics a bit more and have learned about more things than just speed. One of the things we have learned in class was about acceleration. Acceleration isn't only defined as the increase in speed, but can also be defined as the decrease in speed. Acceleration is the change in speed over time. For example, when pressing on the gas pedal of a car, you are accelerating (increasing acceleration). When pressing the brakes, you are decreasing in acceleration. I also learned that gravity has an acceleration of 9.8m/s^2, One of the ways I applied acceleration in real life other than driving a car is when I played Portuguese Horse Shoes. When I throw a ring, it starts of at it's maximum velocity but as time goes by, the drag of the wind, gravity and other factors decrease it's velocity causing it to arch and change direction. Once it changes direction and starts to move down, the gravity increases the ring's acceleration again (in the opposite direction).
