How are forces classified?
force can be classified as contact and noncontact
What best describes a noncontact force?
A noncontact force is a force that can act on an object without physically touching it, such as gravity or magnetic force. These forces can affect objects from a distance.
Is a magnetic force a noncontact force?
Yes, a magnetic force is a noncontact force because it can act on an object without physically touching it. Magnetic fields can exert forces on objects that have magnetic properties.
Is gravity a contact or noncontact force?
contact
How are contact forces and noncontact forces alike and how are they different?
Contact forces and non-contact forces are alike in that they both involve interactions between objects that cause a change in motion. However, contact forces require direct physical contact between objects, such as friction and normal force, while non-contact forces, like gravity and magnetic force, act at a distance without physical contact.
How thermal radiation being measure?
Usually with a noncontact pyrometer.
Is gravity a noncontact force?
Yes. Gravity can be considered a noncontact force. There is no requirement of the force to touch the object which the force exerts itself on.
Is drag a contact or a noncontact force?
Drag is a noncontact force. It is a resistive force that acts on an object as it moves through a fluid, such as air or water. Drag force is dependent on an object's shape, size, and speed.
Why gravity force a noncontact force?
That simply means that it requires no contact between the objects to act.
What is a noncontact force that every object exerts on other objects because of mass?
Universal gravitation.
A noncontact force that causes objects with mass to be attracted toward one another is?
Force of Gravity.
How many forces can be added in a 3-dimensional system?
Any number of forces can be added.. The 3-D system does not limit the number of forces, only their dimensionality.
