What is the word use to describe 'The entire physical universe'?
The term "cosmos" is often used to describe the entire physical universe, including all matter and energy.
How much matter is estimated to exist in the universe?
The estimated amount of matter in the universe is about 27% of its total composition. This matter includes galaxies, stars, planets, and other celestial objects. The rest of the universe is made up of dark energy and dark matter, which are still not fully understood by scientists.
If the area that contains matter is called space then what is the area beyond space where no matter yet exist called?
The area beyond space where no matter exists is often referred to as "void" or "vacuum." It is a hypothetical concept in physics used to describe a region devoid of matter and energy. This idea helps scientists understand the boundaries of the observable universe.
Why is coal called buried sunshine?
Coal is often referred to as "buried sunshine" because it is formed from the remains of plants and organic materials that captured the energy of the sun through photosynthesis millions of years ago. This process transformed these organic materials into coal through heat and pressure over time, effectively capturing the energy of the sun in a concentrated form.
What do you call to a person who becomes dog when the moon is full?
A person who transforms into a dog when the moon is full is often referred to as a "werewolf." This creature is a common figure in various folklore and mythology.
A machine is a device that changes a?
its force and speed and energy
In machines energy is often wasted because of frichion. what forms does this wasted energy take?
The wasted energy due to friction in machines typically transforms into heat energy. This heat energy can lead to inefficiencies, wear and tear of components, and can ultimately reduce the overall performance of the machine.
Is matter and energy conserved in a food web?
Matter and total energy are ALWAYS conserved. However, in a food web, you will often consider the USABLE energy; this gets reduced at each step of the food web.
What form of energy is stored in matter?
The form of energy stored in matter is often referred to as potential energy. This includes the energy stored in the bonds between atoms and molecules, as well as the mass energy equivalent calculated by Einstein's equation, E=mc^2.
How does adding energy to matter by heating it affect the energy of particles?
Adding energy to matter by heating it increases the kinetic energy of its particles. This causes the particles to move faster and collide more frequently, leading to an increase in temperature and often a change in state of matter.
Friction frequently causes some of an objects mechanical energy to be changed to what form?
Friction often causes some of an object's mechanical energy to be changed into heat energy. This is because as two surfaces rub against each other, the energy of motion gets converted into thermal energy due to the resistance of the surfaces.
Where does motion energy go?
Motion energy can be transferred into other forms of energy, such as potential energy, kinetic energy, sound energy, or heat energy, depending on the situation. For example, when a moving object comes to a stop, its motion energy is often converted into heat due to friction.
Scientists classify everything in the universe as?
If they are astronomers, they classify everything as 'interesting'. I think the answer may be something like "matter or energy". In fact, according to Relativity Theory, mass (of matter) and energy are in many ways equivalent. "Mass-energy" is a term often used to refer to this fact. Pretty well everything in the Universe is matter or energy,
What transforms rotational kinetic energy into electricity?
A generator is used to transform rotational kinetic energy into electricity. This involves converting the mechanical energy of rotation, often from sources like wind turbines or hydroelectric turbines, into electrical energy through the principle of electromagnetic induction in the generator's coils.
Can you now or ever make matter out of pure energy?
Myself? No I cannot. However, particle accelerators do it all the time. The kinetic energy of two particles smashing into each other becomes several more particles. Light -- as "pure" an energy as can be imagined -- is often seen as becoming an electron positron pair.
What ia plasma?
Plasma is a super-charged state of matter than can be thought of as an energized gas. When gas gains more energy, it often becomes plasma. As such, plasma often carries and releases large amounts of energy.
What state of matter is coal?
Coal is a solid state of matter. It is a naturally occurring combustible material composed primarily of carbon and other elements, often used as a source of energy.
