Newton's 2nd Law
I now have a better understanding of force and acceleration. This tutorial helped to clarify that "when the force is increased the acceleration is increased" and "less (smaller) mass increases acceleration and larger mass decreases acceleration". However, I am confused with idea that mass and inertia are the same concept because I have believed that mass is anything that takes up space and inertia is related to the movement or lack of movement of an object. Another thing about Newton's 2nd Law is the section that explained applying the law this process seems easy enough to simply plug in the numbers for the given formula yet the task is not that simple as one goes further into the tutorial, because it seems to have an overwhelming amount of information and confusing terminology.

Newton's First Law True "Hair Raising Questions"
The videos that illustrated Newton's first law is a wonderful teaching tool for students in grades three thru four, because students will think it's some magic trick that they can do themselves. This will be great for "inquiry based learning.

Newton's 3rd Still Not so Easy
I still do not feel completely comfortable with my knowledge and understanding of Newton's third law of motion. Unfortantely, I don't have a better understanding of the Mathematical concept F=ma. This part of the Science lesson was not easy to follow and I am not certain how to find the accelerated speed of an object. The hands on examples,and the illustrations/diagrams were a great help for me. This helped me to understand/accept Newton's third law "When object A exerts a force on object B, object B exerts an equal and opposite force backon on object A,regardless of the mass or motion of either object".
