-0All laws and theory’s separate Theory goes with how and why Static friction is always staying still but tires ball anything that rolls is static no movement kinetic action is involved Metallic Bonds between 2 metals electrons move freely Covalent nonmetals and electrons shared coparenting Ionic between metal and nonmetals and electrons passed through other Molecule is covalent it is between 2 nonmetals Compound two different elements water can be both Air resistance is friction force Distilled means pure Independent variables is what the scientist changes varies to experiment | Dependent variables are what is controlled at the end Anything with k in meters is kilometers means bigger kilo is bigger Direct both and inverse opposite Electrons are smaller than both protons and neutrons Fusion of hydrogen is the energy behind gravity stars North pointed at the sun it is summer and opposite of northern hemi is winter Spring and fall are paired | summer and winter are paired Atmosphere and density are connected Altitude and atmosphere have inverse relation Nonzero net force Acceleration up down or change direction Radio waves have biggest wave form gamma the smallest Inner planets are small and rocky outer planets gaseous and big Zero net force means no force is acting on it
