Frequent question: Is attractive force negative?

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.

Is attraction positive or negative?

For example, electrons are negatively charged, and atomic nuclei are positively charged. … 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.

Why is the force of attraction negative?

That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational …

Does a negative force implies attractive nature?

Like charges repel and unlike charges attract. Coulomb’s law describes a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force. … A negative force implies an attractive force. The force is directed along the line joining the two charges.

Can a force be negative?

Negative Force

If the applied force is in opposite direction to the displacement of the moving object then the force will be negative. … Forces that are aimed to the left are usually said to be in a negative direction.

Is a positive force attractive or repulsive?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

Is negative force attractive or repulsive?

When the charges have opposite sign, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).

What is attractive force?

Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.
