A contact force, such as friction. If a car wheel wasn't on the ground there couldn't be friction. A non-contact force could be magnets, the two magnets don't need to touch to repel or attract :)

How does friction affect forward motion?

Friction is when two objects touch each other, either smooth or rough friction causes the object to slow down. Also an unbalanced force is when the net force isn't 0 which causes a object to move and cause friction other than a balanced force is when the net force is 0.


What is something you can see and feel but can't touch?

Sunlight, chlorine...


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.


What do you do when you touch somehing hot on your fingers?

It is natural for the brain to respond of touch something too hot to handle by pulling the fingers away from it.


Is friction a non contact force?

Because it is two surfaces rubbing against each other, in this case it creates heat and possibly static electricity. To touch; contact. If two surfaces rub against each other forcefully this is a contact force.

What force needs to touch something i to effect it?

The force of contact is required to affect something physically. This force occurs when one object comes into direct contact with another, resulting in a push or pull that changes the object's motion or shape.


What is a type of force needs to touch something to affect it?

Contact force. This force only acts upon objects that are in direct physical contact with each other. Examples include friction, tension, and normal force.


What force has to touch something?

A force needs to be applied in order to touch something. This force can be exerted through physical contact or interaction between two objects, causing them to make contact with one another.


Which force needs to touch something to have an effect?

The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.


How does smoking affect the sense of touch?

smoking does not affect on the sense of touch according to smoking and while touching something it actually helps you guess right than bad answer so it does not affect.


What force is created by touching something?

When you touch something, you create a force through the interaction of electromagnetic forces between the atoms of your skin and the atoms of the object. This interaction generates a repulsive force that prevents your skin from passing through the object, allowing you to feel the sensation of touch. The strength of this force depends on factors such as the materials involved and the pressure applied during the touch.


How do you check on your son in boot camp?

You don't. If he needs something, either he or the Commanding Officer will be in touch.


What forces only have an affect on objects that they touch?

Contact forces, such as friction, normal force, tension, and applied force, only have an effect on objects they touch. These forces require physical contact between objects to manifest and influence the motion or deformation of the objects involved.


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.


Do surfaces touch more when there is less force or greater force?

Surfaces will touch more when there is greater force, as the force pushes them closer together. Conversely, when there is less force, surfaces will touch less as there is less compression between them.


Why does electrical outlet is alway hot to touch with something plugged in?

Because it's screwed up and needs to be replaced. Recommend calling an electrician.


What is a force called that requires a touch?

A force that requires a touch is known as a contact force. This type of force only occurs when two objects are in physical contact with each other, such as friction, tension, or normal force.
