Newton's Three Laws of Motion

Newton’s Three Laws of Motion 
Newton’s first law states that an object will stay at rest or in uniform motion in a straight line until a force is upon it.
Newton’s second law states that all existing forces are not balanced. The acceleration of an object is dependent upon two variables. The two variables are, the force on the object and the constant mass and its acceleration of an object. 
Newton’s third law states that for every action there’s an equal and opposite reaction. 
Newton discovered his three laws by using his knowledge in math and physics. In 1686, he showed his three laws of motion to the “Principia Mathematica Philosophiae Naturalis”

Doppler Effect

Doppler Effect  The Doppler Effect is related to frequency and wavelengths.  When an object movies through the air it disturbs the air transmitting the disturbances at the speed of sound. The sound moves as waves and depending on the wavelength it determines the frequency which gives the pitch of the object moving through the air. If the wavelength is short it will have a low frequency giving a higher pitch sound. If the wavelength is long, the frequency will be lower producing a duller pitch. The speed of the sound remains the same no matter the wavelength or frequency of the object passing through the air. It only depends on the state of the air or gas. When a sound source is moving through a uniform gas it will produce sound waves which moves at the speed of sound. The sound source moves slower than the speed of sound, the waves will move away from the source. When the sound source moves upwards in the direction of its motion, the waves will bunch up and the wavelength

Black Holes

Black Holes  A black hole is essentially a dead star that had such a great mass that when it died it formed something so gravitationally strong that light cannot even pass through it. It has so much gravity because the gravity is being squeezed together. A black hole is divided into two parts. The first part is called a singularity, which is the centre of the black hole. This part is believed to be incredibly dense because all its weight is combined into one point in space creating very strong gravity. The event horizon is the second part of the black hole. It gets effected by gravity meaning that anything that enters it will not escape. Spaghettification (which is the gravitational force compressing an object into a long thin shape) will also happen in the event horizon. Spaghettification Black holes take million years to develop. They are developed by stars dying. Stars that have hydrogen atoms collapse from a massive cloud of gas under its own gravity. The nucl
