The center of mass and center of gravity serve two separate purposes. As an individual, your center of gravity and center of mass remains the same. The earth has a center of mass. The moon has a center of mass. The moon does not orbit the earth. They orbit their center of gravity. Their center if gravity is always changing. It is not a fixed point. When an airplane takes off, its center of gravity is one place. As it burns fuel, its center of gravity changes. It might be necessary to change its attitude, which today is done automatically by computers. The computers are checked at the end of the flight by human beings.
What else can I help you with?
How can an object accelerate towards the center without ever getting any closer to the center?
An object can accelerate towards the center without getting closer by changing its direction of motion. This is known as centripetal acceleration, where the object moves in a circular path around the center without moving closer to it.
What is the measure of gravitational attaraction or force or gravity pulling one object toward the center of another object?
In any gravitational interaction, the forces are equal and opposite ... Each object is pulledtoward the center of the other one, and the strengths of the two forces are equal.In daily life on Earth, we call the force that attracts us toward the center of the Earth our "weight".Nobody ever talks about the force of gravity that attracts the Earth toward you, but it's equal.Your weight on Earth is the same as the Earth's weight on you.
What causes acceleration of an object?
Acceleration of an object is caused by the application of a force on the object in the direction of acceleration. This force can be due to factors such as gravity, friction, or propulsion. The greater the force applied, the greater the acceleration of the object.
What is the measurement of the force of gravity pulling an object toward the earth?
The strength of the gravitational forces between the Earth and an object on or near it is called the "weight" of the object. In reality, there are two equal and opposite forces going on. The Earth attracts the object toward it, with a force that is the weight of the object on Earth. At the same time, the object attracts the Earth toward it, with a force that is the weight of the Earth on the object. The forces are equal. When the object is our body, we obsess about the first one. Nobody ever talks about the second one.
What did Albert Einstein think about gravity?
einstein thinks that gravity is not a force at all.It is the shortest path in space time curvature.according to einstein when ever heavier object like sun in space it curves the space around it and the object like earth moves around it.
Does gravity act on an object in the air?
Yes, it does. If it didn't, nothing would ever fall.
What does center of gravity have to do with sports?
if there is no center of gravity, then the equipment we use will just float in the air. And if this happens we wont be able to play that sport ever again!(KIDDING ABOUT THE LAST SENTENCE!)
How can an object accelerate towards the center without ever getting any closer to the center?
An object can accelerate towards the center without getting closer by changing its direction of motion. This is known as centripetal acceleration, where the object moves in a circular path around the center without moving closer to it.
Does the motion of two differently shaped objects differ?
Yes depending on how aerodynamic the object is will affect how the object will move so which ever object is more aerodynamic it will move faster than the other.

Why don't planets simplyfall into the sun?
The planets are pulled around by the suns center of gravity, wort of like what happens when you swing a ball around on a rope, it does not ever hit you because you are in the center.
Has earth ever had gravity?
The earth currently has gravity.
What force causes a object to be heavy?
Gravity makes things heavy. Weight is the effect of gravity on an object's mass. That's the amount of stuff it's made of. The more mass something has, the more gravity tugs it down and the heavier it isWeight is calculated as mass times gravity. Therefore, an object with a mass of 10 kg., in a gravity of 9.8 m/sec2 (approximate value of Earth's gravity) will weigh 98 Newton.Mass also affects intertia. The more mass, the more inertia (resistance to acceleration).What actually gives objects their mass is still a subject of active research. If they ever discover it, the answer will probably be quite complicated.
Does it take the same amount of force for an object to go up against gravity as it does to go down with gravity?
It doesn't take any force at all for an object to go down on account of the influence of gravity. All you have to do is let go of it. If you ever want it to go up, then at some point in the process, you'll have to push it upward with a force that's greater than its weight. (After you finish pushing it and it leaves your hand, gravity is the only force on it again.)
Will you ever be able to have gravity on the moon?
Yes. The moon has gravity and always has.
What causes acceleration of an object?
Acceleration of an object is caused by the application of a force on the object in the direction of acceleration. This force can be due to factors such as gravity, friction, or propulsion. The greater the force applied, the greater the acceleration of the object.
