Question

define friction and motion​

Answer 1

Answer:

Any moving object is said to be in motion.

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

Answer 2

Friction is the force that opposes the relative motion between the two surfaces of objects in contact. The force of friction always acts in the direction opposite to that of the applied force.

Motion is the change in position of an object with respect to its surroundings in a given interval of time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, and speed. ... One can also speak of motion of images, shapes and boundaries.
