- Physics is the study of matter and energy and how they interact with each other.
- The energy can take the form of gravity, motion, light, electricity, radiation and many others.
- The energy that is dealt with in physics can range from sub-atomic particles to galaxies.
- Physics is an experimental science. The scientific method is used to form and test hypotheses (an educated guess or possible explanation) of observations in the natural world.
- All the matter that makes up the human race could fit in a sugar cube, because atoms are 99.9999999999999 % empty space.
- The lowest energy state of a atom is called the ground state.
- Sunlight exerts pressure, or solar radiation pressure.
- The mass of our entire atmosphere is estimated to be some 5.5 quadrillion tons (55 followed by 14 zeros).
- Many physicists believe wormholes (a “shortcut” through space and time) exist all around us but they are smaller than atoms.
- Some of the main physics formulas deal with 1D motion, 2D & 3D motion, the laws of motion, work energy, power, circular motion, gravitation, the properties of matter and electricity.
