Differentiate Between Contact And Non-Contact Forces
Answers
Answer:
Contact forces are forces that are exerted by contacting of two surfaces. For an example, the forces acting on each other when one object is kept on top of another are contact forces. In this case, contact forces arise to balance out gravity, a non-contact force. Contact forces also occur when two objects collide. Under collisions, the contact forces create impulses. Friction and viscosity are two good examples for contact forces. For contact forces, the effect of the force takes place immediately after the force is applied.
What are Non-contact Forces?
Non-contact forces are forces that do not require any physical connection between the two objects involved. Non-contact forces can also be represented in vector fields. Gravitational force, magnetic force, electric forces are some examples for non-contact forces. Since non-contact forces are forces acting on a distance, there is a time gap between a cause and an effect. For an example, if an electromagnet is stopped, the objects attracted to the magnet at a distance will feel a very small time lag. The lag experienced is equal to the time taken for light to reach the point from the object. If the sun vanishes from where it is now, the earth would feel the effect only after 8 minutes (time taken for sun light to come to the surface of the earth).
Answer:
Contact force occurs due to the contact between two different objects. Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects.
