Newtons 2nd law of motion states that the acceleration of a object depends on two factors, and these factors are net force and mass. This way to find acceleration for this law is f = M * A. When you use more force to push an object you can push it faster as you are pushing it harder. When mass increases but force stays the same you can not push it as far as it weighs more.

The 3 Laws of motion are the law of inertia, force and acceleration, and action and reaction. The first law states an object in rest stays in rest, the second one says acceleration is based on net force and the third says for every action there is an equal and opposite reaction. A tendency to do nothing or stay unchanged.   The greater the mass the greater its inertia. Throwing a ball because it stays still unless its thrown and the action is throwing and lastly acceleration is based off how hard its thrown.

The entire range of electromagnetic radiation such as radio waves or gamma rays and scientists use it to learn more about the earths heat.  Amplitude is the maximum strength of a wave that shows energy, intensity, and brightness. Frequency is how short or long the wavelengths are. A wavelength is the distance between two peaks of something, and the longest wavelength is radio waves and the shortest is gamma rays. Shorter wavelengths contain more energy while longer ones contain less.

It begins in a nebula and when gravity pulls enough gas and dust together a planet forms. The path it takes is based off of its initial mass at birth.  Stars are born in nebulae and the sun follows the same path as a normal star but only gaseous materials.

The purpose is to understand luminosity and surface temperature. The four main groups are Main Sequence, Giants, Supergiants, and White Dwarfs and the sun belongs in Main Sequence. Color is usually correlated to how hot the star is because the hotter is burns the brighter it is. Top left is hot and high brightness, top right is cool but high brightness, bottom left is hot but low brightness and bottom right is cool and low brightness.

A galaxy is a gravitationally bound group of stars, stellar remnant, and dust. We classify galaxies based on their shape and the 3 main groups are elliptical, spiral, and irregular. Ellipticals have little dust and old stars, spirals have new stars and irregular have the left over unwanted stars.
