Question

Differentiate between Motion and force of friction.

Answer 1

Hint: Let us understand about motion and friction. The concept of motion is when an object changes its location over time. Displacement, distance, velocity, acceleration, speed, and time are all mathematical concepts used to describe motion. Friction is the force that prevents rigid surfaces, fluid layers, and material elements slipping against each other from moving in the same direction.

Complete step-by-step solution:

SL.NO	Motion	Friction
1.	A change of direction or movement of an object with respect to time is referred to as motion. Displacement, distance, velocity, acceleration, time, and speed are all mathematical concepts used to describe motion.	Friction is the force that prevents rigid surfaces, fluid layers, and material elements slipping against each other from moving in the same direction.
2.	The motion of the object does not involve contact between the surfaces.	Friction will only occur if the objects are in contact with each other.
3.	For example, pushing a block causes it to move in the direction of the applied force, as does throwing a ball.	For instance, walking on the ground, riding a bicycle, and so forth.

Note: Friction is caused by interactions between “rough edges” at the molecular level. Friction is often in the opposite direction of movement. The frictional force that exists between two surfaces while one object is attempting to slide across the other when neither object is moving with respect to the other.
