How Newtons laws are associated with the above areas
1. If a skateboard is at rest it stays at rest and if and an object in motion stays in motion with the same speed and direction unless it is followed by an unbalanced force which is unequal opposing force causing motion.
2. It takes more force to move or act on a skateboard/object than it does for a lighter object.
3. Whenever you push your skateboard so it can move faster it is getting pushed in the other direction equally har. For e.g when a rocket take off the power is pushing down but the rickety goes up.
