Gravity pulls gas to the center of gravity (i.e. the Earth). Less dense gases like helium (in balloons) are displaced by denser gases like oxygen. It also can cause them to be compressed by the gas above, which is what keeps the earths surface pressurized and causes thin air up mountains.
Free fall is the motion of an object falling under the sole influence of gravity, without any air resistance. An example of free fall is when a skydiver jumps out of an airplane and accelerates downward due to gravity pulling them towards the Earth.
An example is a hat sitting on someone's head.
The more mass an object has, the more gravity acts on it. Mass actually is known to affect weight because they both depend on each other. =============================== HONK! Beulah the Buzzer has an objection to raise. Mass does not depend on weight. "Weight" is the name we give to the gravitational force acting on a mass.
To calculate gravity at any altitude, you can use the formula: gravity at altitude = acceleration due to gravity at sea level * (1 - 2 * altitude / Earth's radius)^2. The acceleration due to gravity at sea level is approximately 9.81 m/s^2, and Earth's radius is roughly 6,371 km. Substituting these values will give you gravity at your desired altitude.
The explanation was disappointing, not a particle of supporting evidence
Matter approaching the event horizon of a black hole. The gases have been stripped of their electrons by force of gravity as they accelerate towards the singularity.
Air : actually a mixture of gases.
becuase of the gravity
The law of gravity can't be ignored.
"Natural disasters affect many people's lives."
The law of gravity is inviolate; you can't turn it off.
[object Object]
Contraction is basically when an object(solid) reduces in size due to internal or external forces. Expansion is when the object increases in size due to thse same forces (eg. gravity, pressure.) Liquids and gases cannot expand or contract.
Fossil fuels affect the air by increasing the buildup of greenhouse gases in the atmosphere. As they are burned, the gases they give off slowly increase the atmospheric temperature and cause greater heat retention.
one good example is divorce
Free fall is the motion of an object falling under the sole influence of gravity, without any air resistance. An example of free fall is when a skydiver jumps out of an airplane and accelerates downward due to gravity pulling them towards the Earth.
