Define Frictional force?
In Short​

Answer 1

QUESTION :

Define Frictional force

SHORT ANSWER :

Friction is the resistance to motion of one object moving relative to another.

DETAILED EXPLANATION :

• Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
• Friction is the force that opposes motion between any surfaces that are in contact.
• There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. ... Fluid friction occurs in fluids, which are liquids or gases.

Answer 2

Answer:

whenever a body moves or tends to move over the surface of another body ,a force comes into play which acts parallel to the surface of contact and opposes the relative motion.
