Earth is slowly flattening out. Our planet used to be almost exactly spherical when it just formed, but over time it squashed out. You can test this by taking a piece of salt dough and rolling it into a ball. Then, put it inside a pail with a long string handle. Whirl the pail around your head for a while, then examine the salt dough. It will be flattened.
To make salt dough: Mix salt, flour, and water.
What else can I help you with?
Is there any difference between the value of g at the equator and the poles?
Yes, there is a difference in the value of acceleration due to gravity (g) at the equator and the poles. This is because the Earth is not a perfect sphere and has an oblate shape. At the equator, the centrifugal force due to the Earth's rotation reduces the effective gravity and makes g slightly smaller compared to the poles where this effect is minimal.
What is the acceleration due to gravity at 49 degrees north latitude?
The acceleration due to gravity is not a constant across the face of the earth, as is astutely suggested from the nature of the question. The acceleration due to gravity on earth is given by g , and it is about 9.789 m/sec2 at the equator and about 9.823 m/sec2 at the poles. The observer might conclude with a bit of thought that the effect of gravity at the poles is a bit higher because of the shape of the earth, which is sometimes termed an oblate spheroid by astrophysicists. The earth is flattened up top and down bottom, and is a bit "fatter" in the middle. That means that a body on the equator is farther from the effective center of pull of gravity of earth. It will weigh less on the equator. And more on the poles where gravity is higher. At 49 degrees north latitude, the value of g is some 9.8707 m/sec2 there. Note that the general value often given for g is some 9.8 m/sec2, and it is applied for much work in "regular" mechanics.
Is an object in free fall with less air resistance fall with a greater acceleration?
No, an object in free fall experiences the same acceleration due to gravity regardless of its shape or size. Air resistance does not affect the acceleration due to gravity acting on the object.
Is Weight constant every place in the universe?
No, the earth has a greater pull on a body at the poles, making anything slightly more heavy there. This is for two reason: 1) Because of the shape of the earth, (a slightly flattend sphere) the distance to the core of the planet is greater at the equator and lesser at the poles. Thus, the gravity is greater at the poles. 2) Imagine the earth as a sphere on a vertical stick, spinning really fast. Its not hard to imagine things on the equator being slingshotted away from the earth, while at the top and bottom of the sphere there is no such effect. In reality, ofcourse there is not nearly enough speed for anything to be slingshotted off the earth, but the effect remains in tiny amount, pushing bodies slightly away from the core, and thus creating the effect of decreased weight.
Were would a bowling ball and a napkin fall with the same acceleration?
Both the bowling ball and the napkin would fall at the same rate of acceleration due to gravity, assuming no external forces are acting on them. This is because all objects experience the same acceleration due to gravity, regardless of their size, mass, or shape.
What is the effect of latitude on acceleration due to gravity?
The equation for the force of gravity is F=-GMm/r2 at the equator the earth has more mass due to the gravity of the sun distroting the sherical shape of the earth. But this mean that the distance between the centre of the earth to the poles (r) is less and because r is squared the effect of distance has more of an impact than the mass so this means that gravity is stronger at the poles and weaker at the equator.....
How did gravity affect the earth shape during earth's formation?
earth's shape is influenced by gravity because gravity will pull the objects in space together forming a sphere

How does the planet's gravity effect it?
I makes the planet spheical in shape.
What is the speed of fall on Earth vs on Moon?
The question is somewhat ambiguous. It could be asking either one of two different questions.Here are the answers to both:1). The moon does not fall to earth because it has tangential velocity which, when combined with the force of gravity toward the center of the earth, results in a stable Keplerian elliptical orbit.2). Apples do not fall to the moon because of the following facts:a). The apple's distance from the moon's center is roughly 60 times the apple's distance from the earth's center.b). The earth's mass is roughly 82 times the moon's mass.c). The result is that the gravitational force attracting the apple to the earth is roughly 295,000 times the force attracting it toward the moon.The same situation holds true for all objects on the earth. A car, attracted to the earthwith a force (weight) of 2000 pounds (1 ton), is also attracted to the moon by a forceof about 1/10th of an ounce. When it falls, it falls in the direction of the greater force.
Earth's shape is primarily the result of what factor?
Gravity.
What fore gave earth its spherical shape?
Gravity.

What are Filipino folktales about the shape of the earth?
The earth in Philippine folklore was shaped by a god or creator. The folklore also states that gravity forms the earth into its shape.
What has the greatest effect on the Earth tides why?
The gravitational pull of the moon has the greatest effect on Earth tides. The moon's gravitational force causes bulges in the Earth's oceans, creating high and low tides as the Earth rotates. Other factors, such as the sun's gravity and the shape of the coastline, also play a role in affecting tides.
