The acceleration a system experiences when acted upon by an unbalanced force. This shows the friction that an object experiences when moving. I learned about using my FBDs to calculate the sum of the forces, EFx and EFy, and putting them equal to ma or zero depending if the system is accelerating. I also learned about friction, called mu. This can be figured out from the equation Ff=mu*Fn. Mu is actually a naked number because it is newtons divided by newtons.
I have found finding the mu difficult because sometimes i will not remember the equation. Or finding things with not much information. Also what I found difficult was finding the tension in the string.
My problem solving skills are getting better from the other sections I am now understanding the concepts of the systems. Solving problems, doing classwork, and homework has gotten easier. But I have been a little lazy in my work, but i have started to pick it up on homework and classwork.
