how are contact forces and non contact forces alike?
Answers
Explanation:
contact and non-contact forces. A non-contact force is a force which acts on an object without coming physically in contact with it, as compared to a contact force which, as the name implies, is applied by an object in contact with another object.
Explanation:
Contact and non-contact forces
A non-contact force is a force which acts on an object without coming physically in contact with it, as compared to a contact force which, as the name implies, is applied by an object in contact with another object.
Three examples of non-contact forces are:
- gravitational force,
- electrostatic force (as pictured on the right) and
- magnetic force.
Non-contact forces act through fields. For example gravitational forces are present in gravitational field, magnetic forces are present in a magnetic field and electrostatic forces are present in an electric field.
Examples of contact forces include:
- frictional forces, which occur when to objects rub each other
- drag forces, which occurs when air or other fluid particles collide with the surface of an object moving though the fluid.
- tension forces which are experienced when an object is being stretched.
