How can forces act on an object without touching?
Forces can act on an object without touching it through fields. In the case of gravitational forces, objects are attracted to each other through gravitational fields, without physical contact. Similarly, magnetic or electric fields can exert forces on objects without direct contact.
Why can't forces be felt?
Forces can't be felt directly because they only produce motion or deformation in objects. The sensation of feeling is related to interactions involving touch and pressure, which are caused by physical contact between objects. Forces, such as gravity or electromagnetic forces, do not involve direct physical contact with our sensory receptors, so we do not directly feel them.
Forces can only stop objects from moving true or false?
False. Forces can also set stationary objects in motion.
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.
Why can't you notice electric forces between objects?
Electric forces are typically only noticeable when dealing with objects that have a strong charge imbalance, such as in the case of static electricity or lightning. In everyday situations, most objects have neutral charges overall, which makes the electric forces between them too weak to be perceptible to our senses.
Are forces only exerted when objects touch each other?
No...
Can only solid objects exert forces?
Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
Can forces only affect objects if the object is touched?
I don't think so. The earth doesn't have to touch a rock in order for the force of gravity to pull the rock towards the earth. A magnet doesn't have to touch a paper clip in order to pick it up off the table and pull it all the way to the magnet.

Does color affect cooling time of objects?
color only affects the cooling time of objects if there is light
What are contact forces and which forces are contact?
Contact forces are forces that can only have an effect on objects that they touch, such as when you contact a box and apply force to move it. you might apply a contact force to bend, tear, stretch, compress, or twist and abject. Tension force, friction force, and elastic force are examples of contact forces.
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.
Why can only external forces cause objects to move?
Because of Newton's First Law of Motion.
Why can't you notice electric forces between objects?
Electric forces are typically only noticeable when dealing with objects that have a strong charge imbalance, such as in the case of static electricity or lightning. In everyday situations, most objects have neutral charges overall, which makes the electric forces between them too weak to be perceptible to our senses.
This type of force needs to touch something to affect it?
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 :)
