Question

what is meaning of friction of a force ?
and explain about laws of motion
ll real question ll ​

Answer 1

Answer:

• Friction is the force that resists motion when the surface of one object comes in contact with the surface of another. The mechanical advantage of a machine is reduced by friction, or in other words, the ratio of output to input is reduced because of friction..

• laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration

Answer 2

Answer:

FRICTION is the resistance to motion of an moving object.

FORCE is the push and pull of an object resulting from the objects interaction with another object.
