Week 2

       Acceleration is used a lot in our daily lives, but the things that stick out in my mind most are cars because they are always stop and go or slow down and speed up. When I watch car races they use acceleration a lot. The cars have to decrease their acceleration when they go around corners and then increase acceleration on the straight a ways.The car's speed is not always constant therefore the race cars use acceleration.





Test Questions:

1. What is the acceleration formula?
A:   a = vf-vi
                t


2. Name two things you use everyday that have an accelerometer in them?
A: itouch or an airplane

3. If an object is moving at constant speed what is its acceleration?
A: the acceleration is zero because acceleration is defined as the change in speed.





I pretty much understand the just of how acceleration works i just think i need to spend a little more time practicing solving problems so i get a better understanding of how to solve them.
