Force and Motion

Newton's second law of motion is F=ma. Which is force equals mass times acceleration. So to get the force of something, you would multiply the mass and acceleration. The less force the less the object accelerates, and the mass and force applied effects the acceleration. If the mass increases but the force stays the same, it will not accelerate as high as before. And if you use more force the object will go faster/further. 

Newton's third law is for every action there is an equal reaction. It is called the law of Action and Reaction. Newton's three laws show how things react to forces. Newton's first law is how objects in motion will stay in motion and objects at rest will stay at rest. Newton's second law is how force, mass, and acceleration, effect the way that an object moves. And Newton's third law is showing how every action has a reaction. 

Inertia means the tendency for objects to resist a change in motion, and the more mass the harder the reaction will be. For example, if a car is going fast, and it comes to an abrupt stop, you will get pulled forward due to inertia, and you would have to have a counter reaction. And the mass, force, and acceleration will affect how hard you go forward and backwards. Including all three of Newton's Laws.

The electronic spectrum is a scale of different types of waves from radio to gamma waves. Scientist use these waves all the time for different reasons, we all use radio waves to communicate, like on radios, and walkie talkies. We use microwaves for warming up things like food, and we use visible light to see. Scientist use X-rays for scanning bones, ect. Amplitude is the height of the waves on the scale. It is from the middle to the top. Frequency is the length of the wave, how close they are or how far away they are. The wavelength is the distance between the top of two waves. The waves that have the longest wavelength are radio waves. The waves that have the shortest wavelength is gamma waves. The wavelengths are related to energy because as the wavelengths increase the energy decreases, and as the energy increases the wavelengths decrease. The waves that have the highest energy are gamma waves, and the waves that have the lowest energy are radio waves.
