Physics is the study of the laws of the universe that govern matter, energy, space and time. Physics attempts to discover the nature of these four phenomenae. There are a few different types of physics. Classical mechanics, developed mainly by Sir Isaac Newton, focuses on the forces that act on bodies. Nicknamed after its partial-creator, theories that study motion include Einstein's theory of relativity for large objects and objects moving at very high speeds. Quantum mechanics deals with small objects and the forces exerted on them over small distances. Electromagnetism is the study of electromagnetic fields, how they field affect a charged partical that might happen to be traveling through, and what forces it might exert on the particle. This field of physics deals with light which happens to be a rotating electromagnetic field. Thermodynamics is the branch of physics that deals with heat and the conversion into different forms of energy. Physics tries to study and understand concepts such as gravity, waves, acceleration and velocity, magnetism, electricity, temperature, viscosity, wave-particle duality, the speed of light, and momentum.
If you yelled for 8 years, 7 months and 6 days, you would produce enough sound energy to heat up one cup of coffee. The average ice berg weighs 20,000,000 tons. That's 450 Titanics! The speed of light never changes. Blue light is actually hotter than red light. If something moves at a velocity close to the speed of light, its time will slow down and it will shrink. The pull of gravity inside a black hole is so strong that not even light can escape.
