2. Laws Of Motion
2.1. #1 Law: An object will keep moving with velocity, unless and unbalanced force is added
2.1.1. Inertia
2.1.1.1. tendency to resist change
2.1.1.2. requires mass
2.2. #2 Law: Net Force and Mass affects the acceleration

5.1.1. Force that keeps everything on earth
5.1.2. Force I all the other planets creates the solar system
5.1.3. cant feel the force because its too big to notice
5.2. Factors affecting Gravity
5.2.1. mass
5.2.1.1. matter in an object
5.2.1.2. SI unit for mass is kg
