Orbital mechanics are a direct result of the effect of gravitational force. Without gravitational force, no object would orbit any other - they all would follow their own independent straight line travel.
Also, in reference to this question's inference that gravity pulls downward (i.e. towards the earth), remember that ALL objects, regardless of size, exert gravitational force. Obviously, the larger the object, the larger the gravitational force; and, the closer the object, the more force it exerts. So, in this case, remember that things near the Earth have at least three major gravitational forces acting on them: the Earth, the Moon, and the Sun. All three gravitational forces "pull" in different directions, and exert a different amount of force (based on the exact location of the orbiting object).
The gravitational pull (gravity) is not as strong on the moon. (It is a smaller object) Since it is not pulling you on to a scale as hard, you do not weigh as much. :)
No. An object weighs less on the moon than on Earth. This is because the gravity on the moon is much less than that of Earth, so there is less of a force pulling down on an object.
When on Earth, you can escape if you move away from the Earth at the "escape" speed. Gravity will slow you down and you will reach zero speed at an infinite distance.
If the mass increases then the gravitational force will also correspondily increase as gravity is directly proportional to the mass of the object
Earth would be destroy due to the gravity force of that planet.
mass of object *force of gravity
without gravity there, the planet would float off in a line. it would keep going until a force stops it so says newtons 1st law of motion.
The object can be stationary and have gravity pulling on it ergo no kinetic energy
mass of the object pulling
Most folks call that the object's weight.
yes
Freefall this means the objects is falling through the air while gravity is pulling.
Gravitational Potential Energy.
bad girlfriend...or gravity
Gravitational force.
Perhaps surprisingly, it is called the force of gravity.
It is called gravity, which is defined as the pulling force of an object. Each planet has their own gravity.
