Unit 6
Today in class we started to learn about Unit 6 - Forces that accelerate. Newton's second law is really important in this Unit because it is the Law of acceleration. The Law of Acceleration states that the acceleration of an object is directly proportional to the net force of an object an the acceleration of an object is inversely proportional to the object's mass. If the object is lighter it accelerates faster. If the heavier it accelerates slower. Today we also learned more about force diagrams. One example Mr. Blake told us about was an elevator. For this problem we had to draw a diagram and use equations. Another thing I learned today is that we are and have been ignoring friction because it makes physics really complicated.

I like how you defined the second law and said that lighter objects accelerate faster and heavier objects accelerate slower. It was really clear for me to understand.
ReplyDeletegood picture !You did a great job of explaining newtons second law and then giving examples for it
ReplyDeleteI like how you explained the unit, and nice picture.
