Friction: Friction is the resistance to motion of one object moving relative to another. Force: Force is essentially a push, or a pull action, that can lead to certain outcomes. It can change the state and direction of the motion of an object.
It also can deform the shape and size of the object. Related Doubts What is the difference between static friction force and potential energy? Asked on 20th Nov, View More.

Scientists began piecing together the laws governing friction in the s, but because the interactions are so complex, characterizing the force of friction in different situations typically requires experiments and can't be derived from equations or laws alone.
For every general rule about friction, there are just as many exceptions. For instance, while two rough surfaces such as sandpaper rubbing against each other sometimes have more friction, very smoothly polished materials such as plates of glass that have been carefully cleaned of all surface particles may actually stick to each other very strongly.
There are two main types of friction, static friction and kinetic friction. Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion. In liquids, friction is the resistance between moving layers of a fluid, which is also known as viscosity.
In general, more viscous fluids are thicker, so honey has more fluid friction than water. The atoms inside a solid material can experience friction as well. For instance, if a solid block of metal gets compressed, all the atoms inside the material move, creating internal friction. In nature, there are no completely frictionless environments: even in deep space, tiny particles of matter may interact, causing friction. An object that compresses or stretches a spring is always acted upon by a force that restores the object to its rest or equilibrium position.
For most springs specifically, for those that are said to obey " Hooke's Law " , the magnitude of the force is directly proportional to the amount of stretch or compression of the spring.
