As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

At what temperature will gas molecules in a room be moving the slowest? a. 15°Cb.

Phases of matter

When a solid is heated the particles gain energy and start to vibrate faster and faster. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.

Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.

Heat is a form of energy, and energy is not a form of matter because it is not composed of atoms or molecules.

The particles we’re made of About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. If we lost all the dead space inside our atoms, we would each be able to fit into a particle of lead dust, and the entire human race would fit into the volume of a sugar cube.

No! Neither Time nor Space can exist without the Matter, aka the Universe made up of physical stuff. First, without the Matter there wouldn’t be anything capable to determine the existence of Time or Space. Secondly, Time can only be measured using Matter, namely, interactions between material objects.

Particles from empty space Quantum mechanics tells us that there is no such thing as empty space. Even the most perfect vacuum is actually filled by a roiling cloud of particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness.

Gravity exists everywhere in the universe and is the most important force affecting all matter in space. In fact, without gravity, all matter would fly apart and everything would cease to exist. The strength of gravity is proportional to the mass of the two objects and inversely related the distance between them.

When gravity disappears for 1 second the outwards force balanced by the gravity would be released causing a massive explosion. In other star systems with more immense stars and natural phenomena such as pulsars and and especially black holes the explosions and expansions would be greater.

Definition: Zero Gravity or Zero-G can simply be defined as the state or condition of weightlessness. It also refers to the state in which the net or an apparent effect of gravity (i.e. the gravitational force) is zero.

In terms of absolute magnitude, dark energy is the weakest thing of all: it took the Universe nearly half its age just to begin revealing its effects, and it wasn’t even discovered by humanity until 1998.

Though gravity holds planets, stars, solar systems and even galaxies together, it turns out to be the weakest of the fundamental forces, especially at the molecular and atomic scales.

When scientists looked for a unified theory of the universe they forgot the most powerful unseen force. Love is Light, that enlightens those who give and receive it. Love is gravity, because it makes some people feel attracted to others.

Gravity

Long range force A force that does not need contact between objects to exist. One example is the gravitational force (weight).

Action-at-a-Distance Forces

• Applied Force.
• Gravitational Force.
• Normal Force.
• Frictional Force.
• Air Resistance Force.
• Tension Force.
• Spring Force.

There are different types of contact forces like normal Force, spring force, applied force and tension force.

If you remember any of the physics you learned in school, it’s possible you may remember that there are four fundamental forces of nature. They are in no particular order gravity, electromagnetism, the weak nuclear force and the strong nuclear force.
