Can fire burn in zero gravity?

Fire is a different beast in space than it is on the ground. When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don’t rise. Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.

What is gravitational force affected by?

The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.

Does gravitational force affect everything?

Newton’s law of universal gravitation states that the force of gravity affects everything with mass in the universe. Newton’s law also states that the strength of gravity between any two objects depends on the masses of the objects and the distance between them.

Why does fire burn upwards?

On Earth, gravity determines how the flame burns. All the hot gases in the flame are much hotter (and less dense) than the surrounding air, so they move upward toward lower pressure. This is why fire typically spreads upward, and it’s also why flames are always “pointed” at the top.

Can a fire burn without oxygen?

A fire cannot burn without oxygen. The burning that a star does, then, is a nuclear reaction, and not a chemical one like the fires on Earth (when a candle burns, the atoms themselves remain unchanged: just the molecules are affected).

Does mass affect gravitational force?

Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). The gravitational force weakens rapidly with increasing distance between masses.

Which has more gravitational force?

The greater an object’s mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive.

Does gravity get weaker the higher you go?

gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) gravity is caused by the Earth spinning. gravity affects things while they are falling but stops when they reach the ground.

What is the limit of gravitational force?

The Earth’s gravitational force unlike the Earth’s atmosphere has no limit or boundary. Newton’s Universal Law of Gravitation states that the force is inversely proportional to the square of the distance between the centers of attracting bodies.

Why does gravity not attract smoke?

Smoke particles are only slightly denser than air molecules, and often have a flat shape, so the pull of gravity isn’t strong when acting on the small smoke particles, which resist being pulled down through the air.
