4 Forces and Motion: Stop Faking it!
Newton's Second Law is evident to everyone who has tried to move any object at a certain distance. A greater force is required to move a heavier object as compared to a lighter one for a certain distance. Newton's Law has quantified this concept providing us with a mathematical formula to understand it better. The presentation is simple enough to grasp the relationship of the variables. Clear and specific examples were very helpful even for an eager learner.

4 Force and Motion
It always been a difficult to understand forces you cannot see but feel, one of these forces is centripetal force which is any motion in a curved path, and requires a force directed toward the center of curvature of the path. This is also referred to as "center seeking" force. With the illustrations accompanied with simple explanations, some of the concepts are a little less daunting.
