Newton's Second Law

This is what I learned about Newton's Second Law:


In Newton’s Second Law it is about how an object will change in velocity if something pushes of pulls it. It explains that the force will cause the object to change in velocity and to accelerate. The acceleration of the object is directly proportional to the force. Example: If Carly pushes the book across the table and it accelerates but if she pushes five times harder then the acceleration would be five times greater. I also learned that the acceleration is inversely proportional to the mass of the object.



What I have found difficult about what I have studied is:

The only thing that I am struggling with is the friction part of Newton's Second Law. Not a lot of known variables are given in these types of problems so I easily get overwhelmed and defeated. However, once I sit down and actually concentrated I can, eventually, figure it out.



My problem solving skills:

My problem solving skills have definitely improved greatly opposed to the pervious trimester. However, I think my main problem solving issue was that I was clearly not trying hard enough the first trimester. I enjoy the topic that we are currently discussing and understand most of Newton's Laws.

Inertia

Part A:

This is what I learned about Newton's First Law...The main idea in Newton's first law is that it deals with forces and changes in velocity. If an object is moving along at a steady constant speed then it will continue to move at constant speed. ( Restating:If there is no net force resulting from unbalanced forces acting on an object, then the object will continue to have a constant velocity. If that velocity is equal to zero then the object stays a rest.) An object that is standing still and no other forces contact it then it will remain still.What I have found difficult about what I have studied is mass and wieght. Sometimes I can not recall how to set up the equation. Also, I forget the fact that weight(vector) is different from mass(scalar).My problem-solving skills were horrible last trimester. I just could not seem to get it together . That trimester I had trouble with graphs,acceleration and constant velocity (50% of the unit I would say, that confusion is dispalyed in the grade I got). However, the classwork and the homework over equilbruim and torque seemed easy to me. I think that I have obtained a full grasp on both of these topics and the problem-solving that you have to do within the problems.


Part B:
All around us Newton's first law is being used constantly. Take my uncle for example he is a  pilot that commutes from one city to the next. He uses the first law when he changes the setting of the airplane’s engine. The famous NASA, uses the law when launching a rocket straight up into the air. Even when a little child is outside on a bright sunny day flying his bright red kite can be an example of Newton’s first law when the wind changes.

HELP!!!!

Does anyone know how to copy a screen into paint? I am pressing ALT and then the Print Screen button at the same time but how do you paste it into paint?
