When there is no net force of gravity, all the opposing forces of gravity cancel out. For example, most of the way to the moon, the gravity pulling from the moon would cancel out the gravity from the Earth. At that point, there would be no net force of gravity.
KEEP IN MIND, that this is something very different from the weightless feeling you get when falling. When falling, gravity still affects you (hence you accelerate downwards). If there is no net force of gravity, gravity will not affect you at all.

A rock is thrown vertically into the air At the very top of its trajectory the net force on it is?
The net force is gravity. The speed is zero.
What does gravity effect the motion of objects?
Gravity provides a force; any net force will result in an acceleration, i.e., a change of motion.
Is there any difference in the strength of the force of gravity on land compared to in water?
The force of gravity on the same on land and water.However, in water, there is an upward force of buoyancy which acts in an opposite direction to the force of gravity. Hence, in water, the total net force downward is lower.
When two forces are acting in the opposite direction how do you calculate the net force?
gravity
What force causes mass movement?
gravity is the main cause of mass movements.
What do you get when the force of air Resistance from the force of gravity?
The net force on a following object
What is the net force of weightless object?
well, the amount of net force caused by gravity is zero. but its net force caused by other things depend on what forces are influensing it.
What is the net force of gravity tension friction and air tension?
The net force refers to the vector sum of the individual forces.
A rock is thrown vertically into the air At the very top of its trajectory the net force on it is?
The net force is gravity. The speed is zero.
What way is the net force acting on a ball thrown in the air with upward velocity?
net force is non zero because if net force was zero the body would continue to remain at rest according to newtons 1st law....the net force is only due to gravity
What does gravity effect the motion of objects?
Gravity provides a force; any net force will result in an acceleration, i.e., a change of motion.
What is the direction of the net force on a falling sky diver before reaching terminal velocity?
If he's moving with constant velocity, then the net force on him is zero. The force of gravity must be exactly balanced by the force of kinetic friction between him and the air.
Is there any difference in the strength of the force of gravity on land compared to in water?
The force of gravity on the same on land and water.However, in water, there is an upward force of buoyancy which acts in an opposite direction to the force of gravity. Hence, in water, the total net force downward is lower.
Could the net force ever be zero?
Not ever on earth or somewhere with gravity
When two forces are acting in the opposite direction how do you calculate the net force?
gravity
What force causes mass movement?
gravity is the main cause of mass movements.
Why can you jump higher on the moon than the earth?
When you jump, you exert a force greater than the force of gravity to achieve a net positive upward acceleration - at least until your feet leave the ground and you quit exerting force. The net upward force is Fnet = (force you push off with) - (force of gravity) Because the moon has less mass than the earth, the force of gravity is less. As a result, the force you exert to jump on earth would give a higher net upward acceleration on the moon and allow you jump higher.
