What is the meaning of the statement 'some forces can act over a distance rather than by contact' mean?
Forces such as electrostatic or magnetic attraction or repulsion, and that of gravitational attraction will act between two bodies even though the bodies are not in contact.
What happens to the electrostatic force if one charge is quadupled?
If one of a pair of charges is quadrupled and the distance between them doesn't change, then the electrostatic force between them is also quadrupled.
Electric force is a contact force or force at a distance?
electrostatic force is not a contact force it is force at a distance likely to that of gravitational force.
What type of transfer of energy can take place with little or no matter present?
Some forces, such as gravity or the electrostatic force, can act without direct contact. If a force is applied over a certain distance (such as, when an object falls), work is done, i.e., energy is transferred. Ah, but what is direct contact? One electrostatic field pushing against another? If I touch something, it is the electrostatic fields pushing against each other. There is no direct contact!
What will halve the magnitude of the electrostatic force of attraction between two charged particles?
In order to reduce the magnitude of the electrostatic force between two charged particles by half, you canEITHER: reduce the magnitude of the charge on either one by 50% of its original value,OR: increase the distance between the particles to 141.42% of the original distance.
What three forces act from a distance?
Gravity, magnetism, and electrostatic.
What 4 forces act from a distance?
Gravity, magnetism, and electrostatic.
What three forces can act from a distance?
There are only two forces that act at a distance:gravity, andelectromagnetism.Magnetic fields are sometimes referred to as a third force, however magnetism and electrostatic forces are both examples the electromagnetic force.

Forces such as electrostatic or magnetic attraction or repulsion, and that of gravitational attraction will act between two bodies even though the bodies are not in contact.
Forces that act on an object at a distance?
Some forces do not involve physical contact between the bodies on which they act. They act through the space between them. Such forces are called Non-Contact Forces or Action-at-a Distance Force. They are of three types, namely, magnetic force, electrostatic force and gravhtational force. Magnetic Force -- The forces which a magnet exerts on iron objects is called magnetic forces. Electrostatic Force -- The force which result due to the repulsion of similar charges or attraction of opposite charges is called electrostatic force. Gravitational force -- The force by which Earth pulls the objects towards its centre is called gravitational force.
What is a force that works at a distance?
Gravitational, electrostatic, strong nuclear, and weak nuclear
What force works from a distance?
Gravitational, electrostatic, strong nuclear, and weak nuclear
What happens to the electrostatic force if one charge is quadupled?
If one of a pair of charges is quadrupled and the distance between them doesn't change, then the electrostatic force between them is also quadrupled.
Electric force is a contact force or force at a distance?
electrostatic force is not a contact force it is force at a distance likely to that of gravitational force.
Is electro static a contact or a non contact force?
Electrostatic forces work at a distance. Non contact.
Describe the relationship of electrostatic force between two charged objects?
The electrostatic force between two charged objects is inversely proportional to the distance of separation between the two objects. An Increase in the separation distance between objects decreases the force of attraction or repulsion between the objects.
