A) This is what I learned about Newton's First Law. I learned an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is Newton's First Law and it basically means that unless stopped, an object will keep going forward. In a frictionless plane, an object will never stop because there is no opposing force against it.
What I have found difficult about what I have studied is the x component and y component. I was not sure whether to put cos or sin. I always assumed cos with the x component and y with the y component but I learned how to fix this problem.
My problem-solving skills have definitely increased since the beginning of this unit. It was hard starting with a new teacher but I figured out how to solve the problems easier. The subject material is now like the back of my hand.
B) Can you make any connection(s) between what we studied and everyday life, history, situations in the world, any other subject you are studying or your own life?
In a car crash, you must always wear seat belts or you will keep moving until you hit the glass. a hockey puck sliding along ice does not move forever; rather, it slows and eventually comes to a stop. According to Newton's first law, the puck comes to a stop because of a net external force applied in the direction opposite to its motion.
