What happens to gravity as you increase altitude?

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.

Why does acceleration due to gravity decreases with increase in altitude?

Acceleration due to gravity increases/decreases with increasing altitude Acceleration due to gravity. Acceleration due to gravity increases/decreases with increasing depth. (assume the earth to be a sphere of uniform density). Acceleration due to gravity is independent of mass of the earth/mass of the body.

Why does the value of g decrease with altitude?

Consider earth to be a sphere of radius R and mass M. Thus, as we go above the earth’s surface acceleration due to gravity goes on decreasing.

At what altitude does gravity decrease?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s−2 per 3,200 km.)

How does the force of gravity decrease?

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.

What are the two factors affecting gravity?

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Why does gravity vary from place to place?

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.

What factors affect gravity?

How does distance affects gravity?

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

What factors affect a planet’s gravity?

A planet’s size and mass determines its gravitational pull. A planet’s mass and size determines how strong its gravitational pull is.

How does the acceleration of gravity change with altitude?

The gravitational acceleration decreases with altitude, as shown by the solid line in Figure 1 (left). g is equal to 9.5 m/s 2 at 100 km altitude, which is 9\% larger than 8.7 m/s 2. However, at 500 km altitude, g is close to 8.45 m/s 2, which is close to 3\% smaller than 8.7 m/s 2.

How do you calculate the gravity of an aeroplane?

If an aeroplane flies at a distance of 40 km above the earth’s surface then the gravity, g 2 is calculated by equating the ratio of acceleration due to gravity, g 1 and g 2 to square of ratio of the radius. This gives g 2 as 9.67 m/s 2.

What is the value of gravity at the earth’s surface?

Also, as the surface of the sphere increses with r 2 where r is the radius of the sphere and the gravitational field needs to be evenly distributed over the surface of the sphere, so we can say that the gravitational field depends on 1 r 2 . Now, gravity at the earth’s surface is g= G m e r 2 where r= radius of earth.

What is the relationship between gravity and distance?

Now, gravity at the earth’s surface is g= G m e r 2 where r= radius of earth. So, we see that gravity depends inversely with distance. According to gravitation theory, everything with mass emits tiny particles called gravitons which are responsible for gravitational attraction.
