Why the gravitational force is a negative value?
Gravitational force is a vector quantity, meaning it has both magnitude and direction. The negative sign indicates that the force acts in the opposite direction to the reference direction chosen, typically taking downward as positive. This convention helps to easily incorporate the effects of gravitational forces in mathematical equations.
Why gravitational potential is negative?
Gravitational potential is considered negative because work needs to be done to move an object from an infinite distance to a certain point in the gravitational field. As the object moves closer to a massive body, the potential energy decreases, resulting in a negative value to reflect the work done against the gravitational force.
Why does an electric force stronger than gravitational force?
The electric force is stronger than the gravitational force because electric charges can be positive or negative, allowing for attractive and repulsive interactions, while gravity is always attractive. Additionally, the strength of the electric force is determined by the charge of the particles involved, which can be much larger than the masses involved in gravitational interactions.
Does a vacuum space have gravitational force?
No, there is no mass there to have any gravitational force.
In which direction will the drag force act if the gravitational force is less than the buoyant force?
If the gravitational force is less than the buoyant force, the drag force will act in the opposite direction of the gravitational force.

Is gravitational force positive or negative?
Gravity force is always downward and it depends how you define the coordinate system. By convention down is negative, but that is only a general rule
What is an gravitational force exerted on an object?
The gravitational force exerted on an object, according to classical mechanics, is the product of the gravitational constant, the object's mass, and the mass of the object exerting the gravitational force divided by the square of the magnitude of the position vector starting from the object exerting the gravitational force and pointing to the object which we are measuring the force exerted onto. And all of this is times the negative of that same position vector.
Why gravitational potential is negative?
Gravitational potential is considered negative because work needs to be done to move an object from an infinite distance to a certain point in the gravitational field. As the object moves closer to a massive body, the potential energy decreases, resulting in a negative value to reflect the work done against the gravitational force.
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
Why does an electric force stronger than gravitational force?
The electric force is stronger than the gravitational force because electric charges can be positive or negative, allowing for attractive and repulsive interactions, while gravity is always attractive. Additionally, the strength of the electric force is determined by the charge of the particles involved, which can be much larger than the masses involved in gravitational interactions.
Is a black hole an example of negative pressure?
Yes, black holes are an example of negative pressure. This is because they exert gravitational force so strong that nothing, not even light, can escape from them, creating a region of extreme gravitational pressure.
What is retardation in physics?
Retardation is the application of a force that produces negative accelleration. Synonyms would be braking, decelleration, damping, etc. Gravitational force operates downward (in a negative direction) so, in most frames of reference, gravity is a retarding force.
Does a vacuum space have gravitational force?
No, there is no mass there to have any gravitational force.
In which direction will the drag force act if the gravitational force is less than the buoyant force?
If the gravitational force is less than the buoyant force, the drag force will act in the opposite direction of the gravitational force.
How is weight affected by gravitational force?
how is weight affected by gravitational force?
When is gravitational force the strongest?
Gravitational force is the strongest when you are the closest to a mass.
