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 object launched into space has rocket motors with more force taking it away from Earth than Earth's force of gravity has in pulling the object toward its center.
lots of thrust.
Gravity, its weight.
No, the more mass of an object the more gravity it exerts.
Mass is the amount of matter in the object. Weight measurement of force that gravity is exerting on the object.
Gravity and Resistance Under free fall, the only force acting upon an object is the force of gravity. But realistically, there is also the force of friction from the air (Air Resistance) that opposes the force of gravity.
gravity :)
The object launched into space has rocket motors with more force taking it away from Earth than Earth's force of gravity has in pulling the object toward its center.
By applying an upward force on the object that is greater than the downward force of Earth's gravity acting on it. Somewhat the same thing that you do with your leg muscles when you walk upstairs, or go in for a jump shot.
9.8
You don't specifically need a magnet to overcome the force of gravity; ANY force that is stronger than gravity can "overcome" it, at least temporarily. For example, if you lift an object up, you are "overcoming" the force of gravity.
Gravity, its weight.
The only force acting on a projectile once launched is gravity. So the acceleration of any object launched at any angle is the acceleration due to gravity, -9.8m/s2.
In general, it will have the effect of speeding such an object up.
GRAVITY... gravity means that objects are "attracted" to other objects, and the larger the object, the more GRAVITY will "attract" the object. The sun's gravity is too large for the planets to overcome.
No, your weight is just the acceleration due to the Earth's gravity,
The upward force would have to overcome gravity, so the force should be F > -mg. Since the upward force and gravity work in opposite direction you can disregard the mass of the object (they cancel: F(gravity) = F(upward) => mg = -m(g+x)) . Consequently the object's mass is irrelevant.
The force of gravity pulls it down to the earth.
Gravity and the upward force of the surface the object is resting on.
