Where on an imaginary gravitational field line between Earth and moon, a mass would have no weight neither due Earth nor due to moon?
rock.freak667 said:If you mean when the gravitational force is zero, then you just need to equate
FEarth and FMoon for a mass m and solve for the distance.
Redbelly98 said:No, that 1/6 figure is only true about the surface gravity of the Earth vs. the surface gravity of the moon. It is not applicable everywhere in space.
I think you really do need to set up an equation using the equation for gravitational force. At least, I can't imagine solving it any other way.
A gravitational field line is an imaginary line that represents the direction and strength of the gravitational force at different points in a gravitational field. It is drawn as a series of arrows pointing towards the center of mass of the object creating the field.
The closer the gravitational field lines are to each other, the stronger the gravitational force is at that point. Conversely, the farther apart the field lines are, the weaker the gravitational force is.
Near a planet or other massive object, gravitational field lines are closer together and more concentrated, indicating a stronger gravitational force. As you move farther away from the object, the field lines become more spread out and weaker.
Yes, gravitational field lines can be used to predict the behavior of objects in a gravitational field. Objects will follow the path of the field lines, moving towards the center of mass of the object creating the field.
Electric field lines represent the direction and strength of electric fields, while gravitational field lines represent the direction and strength of gravitational fields. Additionally, electric field lines can be positive or negative, while gravitational field lines are always positive and point towards the center of mass of the object creating the field.
