Using Newton’s law of gravity, we find that the force of earth’s gravity on your body at the equator is 9.798 m/s2 times the mass of your body, whereas at the poles it is 9.863 m/s2 times the mass of your body. The earth’s centrifugal force also varies with latitude.

It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth’s oblateness. The measured value is larger because the earth’s density is not uniform but increases toward the center.

The effective acceleration of gravity at the poles is 980.665 cm/sec/sec while at the equator it is 3.39 cm/sec/sec less due to the centrifugal force. If you weighed 100 pounds at the north pole on a spring scale, at the equator you would weigh 99.65 pounds, or 5.5 ounces less.

The variation in apparent gravitational acceleration (g) at different locations on Earth is caused by two things (as you implied). The distance between the centers of mass of two objects affects the gravitational force between them, so the force of gravity on an object is smaller at the equator compared to the poles.

According to some calculations, the Earth is losing 50,000 metric tons of mass every single year, even though an extra 40,000 metric tons of space dust converge onto the Earth’s gravity well, it’s still losing weight.

Canada Has An Anti-Gravity Area Hudson Bay has less gravity as compared to the rest of the world.

Essentially, gravity holds our world together. In addition, gravity is weaker at the equator because of centrifugal forces produced by the planet’s rotation. Gravity is also a bit weaker at higher altitudes, being farther from Earth’s center, such as the summit of Mount Everest.

gravity increases with height. 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.

A lack of gravity would eventually take its toll on our very planet, writes Masters. “Earth itself would most likely break apart into chunks and float off into space.” Without the force of gravity to hold it together, the intense pressures at its core would cause it to burst open in a titanic explosion.

Yes. Free fall is defined as “any motion of a body where gravity is the only force acting upon it.” In the vacuum of space, where there are no air molecules or supportive surfaces, astronauts are only acted upon by gravity. Thus, they are falling towards Earth at the acceleration of gravity.

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.

Answer 2: No, heavier objects fall as fast (or slow) as lighter objects, if we ignore the air friction. The air friction can make a difference, but in a rather complicated way. The gravitational acceleration for all objects is the same.

In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. The spacecraft, its crew and any objects aboard are all falling toward but around Earth. Since they are all falling together, the crew and objects appear to float when compared with the spacecraft.

A perfect vacuum is defined as a state with no matter particles, and also no photons. This state is impossible to achieve experimentally because it is nearly impossible to remove the matter, and is impossible to eliminate all the photons.

Outer space has very low density and pressure, and is the closest physical approximation of a perfect vacuum. But no vacuum is truly perfect, not even in interstellar space, where there are still a few hydrogen atoms per cubic meter.

Because the maximum theoretical vacuum at sea level is 29.92 in. -Hg, actual pump capabilities are based on and compared to this theoretical value. Depending on pump design, the vacuum limit ranges from 28 to 29.5 in. -Hg or about 93% or 98% of the maximum theoretical value.

that a vacuum does not exist in nature even though no one on earth can produce such a space that is completely empty of all matter. that air is an exhalation or corporeal effluence of the earth. 2. that the earth retains this air with a certain weight for its own preservation.

We cannot breathe in space because there is no air in space. Without air in your lungs, blood will stop sending oxygen to your brain and you’ll pass out after about 15 seconds. 90 seconds after exposure, you’ll die from asphyxiation.
