Do objects have to touch for a force to be involved?
No.
Force that opposes the motion of objects that touch as they pass?
Friction
Is static a contact or non-contact force?
it is a noncontact force because before two objects touch, the electical charge held in one of the objects will "jump" to the other object, causing a static shock
What two charged objects are made to touch each other and then separate?
In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.
This exerts a force on anything that has an electrical charge?
An electric field has what are called lines of force that radiate outward from the electric charge that creates them. It is the "touch" or the interaction with these lines of force that allow an electric field to exert a force (an electrostatic force) on anything with an electric charge.A fundamental law of electrostatics is that like charges repel and opposite charges attract. A charge will have an electric field around it, and if another charge is nearby, the fields of the charges will interact. Like charges will "push" on each other, while opposite charges will "pull" on each other. It's the fields of the respective charges that interact to cause the effects we see.All electric charges have associated electric fields around them. It is possible to "see" the electric fields like we "see" gravimetric fields. Both forces can "reach across" space to interact with objects at a distance from the source of the force. The field lines (lines of force) carry the force outward and are the means by which interaction occurs.
Do objects have to touch for a force to be involved?
No.
What electric line of force can touch?
the lines of force are not real. these lines of force are imaginary lines. so we can not touch it.
Does induction require objects to touch?
No induction does not generally require the objects to touch. Induction can mean that one object induces an electrical change in the other object from a distance
What is a force only exerted when objects touch?
A contact force? The answer really depends on the level of the question. Primary school answer: A pushing or pulling force, or a friction force occur when objects touch. High school answer: Same as above, but 'pushing' and 'pulling' would be replaced with positive and negative. Friction would be defined as a force that opposes motion, and would include air resistance and drag. University answer: Technically, there is no such force, as all forces act at a distance without touching. In fact, objects don't actually 'touch' one another at all. The outer electrons in an object's atoms will repel said electrons from another object's atoms through the electromagnetic force. This only makes it feel like the objects have come into contact with one another, when in fact they haven't.
Force that opposes the motion of objects that touch as they pass?
Friction
What force makes objects touch?
gravitational, electrostatic, and magnetic forces
What is the force that opposes the motion of objects that touch as they move pass each other?
Force of push or pull
Difference between contact force and those actata a distance?
Contact force means that objects need to be in contact for there to be a force. "Action at a distance" means the objects do NOT need to touch one another directly.
What is a contact force?
when two objects need to touch each other to work, an example for a contact force is static electricity. !
How do swimmers use touch pads?
Swimmers use touch pads by touching them with their fingers or hand. They have sensitive sensors that do not require great force to have them register the touch.
Is static a contact or non-contact force?
it is a noncontact force because before two objects touch, the electical charge held in one of the objects will "jump" to the other object, causing a static shock
