The strength of the gravitation force between two objects depends upon the distance between the two objects and their masses. F = (M1*M2*G)/R2 (Newton's Law of Gravitation) Here M1 and M2 are the masses of the two objects, G is the universal gravitational constant, and R is the distance between the two objects. If the masses of the two objects are large the attraction between them will also be large. However, as the radius increases the gravitational force between the two decreases by the square of the distance. So, the gravitational force depends mainly upon the distance between the two objects, but also significantly upon the masses of the two objects.
The answer to this question is no. Radiation can occur when objects are not touching
If the objects are not tied together, and if the gravitational forces between them are negligible in their current environment, then the distance between them has no effect whatsoever on their motion.
Objects with the same electrical charge repel each other due to the electrostatic force. This force is caused by the interaction of the electric fields surrounding the charged objects, causing them to push away from each other.
Potential energy is stored energy due to the interaction between objects or particles, typically based on their positions relative to each other. It can be gravitational, elastic, chemical, or electrical potential energy, among others.
The interaction between two like-charged objects is repulsive. The interaction between two oppositely charged objects is attractive.
Comparable with what? You can compare the electrical force with other forces. For example, if you compare it with gravity, it turns out that both are inverse-square laws. While gravity acts on ANY mass, the electrical force only acts on electrically charged objects. And while gravity is always attractive, the electrical force can be both attractive and repulsive.
Interaction force is the force acting between two objects as a result of their interaction, such as gravitational, electromagnetic, or nuclear forces. Interaction distance is the distance between the centers of mass of the interacting objects at which the interaction force becomes significant enough to influence their behavior.
The force between two moving objects is called the force of interaction or the force of interaction between two objects. This force can be attractive or repulsive, depending on the nature of the objects and their velocities.
When you don't have gravitational interaction between objects.
If two uncharged objects are brought near each other, there will be no significant interaction between them. Since they are uncharged, there are no electrical forces at play that would cause them to attract or repel each other.
... the gravitational force between them, and the electrical force if the objects are charged.
An example of interaction at a distance is gravitational attraction between two objects, such as the pull between the Earth and the moon, or between the sun and planets in our solar system. This force operates without any physical contact between the objects involved.
Charged objects can interact through the electric force, which can be attractive or repulsive depending on the charges (opposite charges attract, like charges repel). The strength of the interaction depends on the amount of charge on each object and their distance from each other.
The conservation of momentum symmetry states that in a closed system, the total momentum before a physical interaction between objects is equal to the total momentum after the interaction. This means that the combined momentum of all objects involved remains constant, showing that momentum is conserved in the interaction.
