If the strong nuclear force residue ceased to exist only Hydrogen nuclei could exist as the binding energy for heavier elements would no longer exist. If either force ceased to exist all stars would be unable to produce energy by fusion. The Universe would become a very cold place.

Frist of all, we need to know that like charges repel and opposite charges attract. The nucleus is made up of neutrons and protons. If the strong force didn’t exist, there would be nothing but hydrogen and neutrons floating in space.

When it comes to physical ability, the human being is one of the weakest and most physically pathetic creatures on the planet. Turtles have shells to protect them. Tigers, lions and bears have sharp teeth and claws.

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. This called Coulomb’s law and was the first attempt to understand the electric force. Like the gravitational force, the Coulomb force is an inverse square law.

A stable state of a bond is when attractive forces balance repulsive forces. “A stable state between two atoms or two molecules is when they attract each other with a force that equals the force that they repel each other.” Chemical bonds release energy when they form.

A: The equation a=F/m or the acceleration is equal to the net force of an object divided by that object’s mass, is an equation derived and explained by Sir Issac Newton’s second law of motion. Newton’s second law of motion states that the force of an object is equal to the mass times the acceleration of that object.

There are numerous attractive forces prevailing in nature. Some of them are magnetic force, electric force, electrostatic force and gravitational force. Gravitational force is very well-identified instance force of attraction as it draws objects towards itself regardless of its distance.

In general when the force is attractive, the potential energy is negative and as shown above force will be negative. In case of repulsion, with the same argument, the force will be positive.

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

The minus sign is to indicate that the force is attractive: if there was no minus sign, two masses would repel.

9. When they are connected with a wire, the spheres will evenly divide the total charge. Also, an attractive force is negative, and a repelling force is positive.

A trapped particle (trapped by an attractive force) requires energy to be freed, hence describing it as having negative potential energy. Another way to think of it is that an attractive force causes the distance between two bodies to shrink, and their relative velocities are becoming increasingly negative.

The electric force F E F_E FE​F, start subscript, E, end subscript can be either attractive or repulsive. Opposite charges, such as a positive charge and a negative charge, attract each other.

This is a negative value for two reasons; the force acting between them is attractive, and the zero of potential energy is at infinite separation. This is a negative result if the force between the two charges is attractive (they are opposite) and positive if it is repulsive (the charges are similar).
