Question

what is force? what is friction? ​

Answer 1

Answer:

force- A force is the change of state of an object due to external surrounding

friction- friction is the force resisting the relative motion of solid surfaces,fulid layers and materials elements sliding against each other

Answer 2

${\tt{\red{\underline{\underline{\huge{Force}}}}}}$

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

${\tt{\blue{\underline{\underline{\huge{Friction}}}}}}$

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
