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).
In a gravity-less environment, an object would have no weight because there is no gravity pulling it down. Weight is the force of gravity acting on an object, so without gravity, there is no weight.
The mass of an object determines the strength of its gravitational pull, as described by Newton's law of universal gravitation. Weight, on the other hand, is the force of gravity acting on an object's mass. The greater the mass of an object, the greater the force of gravity pulling it towards another object with mass.
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. :)
On the moon, gravity is about 1/6th of the gravity on Earth. Therefore, if you weigh 100lbs on Earth, you would weigh approximately 16.6lbs on the moon. This is because the force of gravity pulling you toward the moon is much weaker compared to the force of gravity pulling you toward Earth.
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.
The amount of gravity pulling on an object is called weight. Weight is the force exerted by gravity on an object's mass.
Weight is a measure of how strongly gravity is pulling on an object. It is the force exerted by gravity on an object's mass.
In a gravity-less environment, an object would have no weight because there is no gravity pulling it down. Weight is the force of gravity acting on an object, so without gravity, there is no weight.
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
The force of gravity on an object or person is known as weight. Weight is the measure of the force of gravity pulling on an object's mass.
Most folks call that the object's weight.
The pull of gravity on an object is called weight. It is the force that acts on an object due to gravity pulling it towards the center of the Earth.
The pulling force caused by gravity is called weight. Weight is the measure of the force of gravity acting on an object mass.
The force of gravity pulling down on an object depends on its mass and the acceleration due to gravity (9.81 m/s² on Earth). The force can be calculated using the formula F = m * g, where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity.
Weight, of the object is on dying bannanas.... quickly dying bannanas happy x-mas and!@#!@$!$#$#@4 you
