What can apply an attractive or repulsive force?

Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive. The inverse square relationship between force and distance that is woven into the equation is common to both non-contact forces.

Which type of force can have both attractive and repulsive forces?

Unlike the other two fields, which can involve both attraction and repulsion, gravity only acts by attraction. All objects attract each other by gravity, but these attractions are too weak to notice unless one object contains a huge amount of matter (stuff).

What is an example of a repulsive force?

Repulsive force (magnetism) between magnets of opposite orientation. A compressed material repelling bodies on both sides, e.g. according to Hooke’s law. Repulsive force (biology), associated with involuntarily vomiting, as in response to ingestion of a toxin.

How do you know if a force is attractive or repulsive?

If both the interacting particles are positively or negatively charged, then the force is repulsive. If both the interacting particles are of opposite charges then the force is attractive in nature.

What is attractive and repulsive forces in physics?

Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike. … Repulsive forces occur only when atoms are very close to each other.

What is an 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.

What is an repulsive force?

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

Is strong nuclear force attractive or repulsive?

The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 1.0 × 1015 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At distances less than 0.7 fm, the nuclear force becomes repulsive.

Is gravitational force attractive or repulsive?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

Can electric force be attractive and repulsive?

Comparing Electrical and Gravitational Forces

Both equations show an inverse square relationship between force and separation distance. … Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive.

Is the force between two like masses attractive or repulsive?

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 size of the force varies inversely as the square of the distance between the two charges.
