Why friction made it diffcult to discover newtons first law of motion?

Answer 1

Newton's first law of motion categorizes any force affecting the motion as an external force. Friction being an external force, negates its presence as an integral force of a motion. Hence friction cannot be used to observe first law of motion.

Answer 2

Newton's first law states that every object will continue in its state of rest or uniform straight line of motion unless acted upon by an outside force. In other words an object in motion will stay in motion unless acted upon. Friction made it difficult to discover this law because friction is an outside force acting upon an object. Like rolling a ball down a side walk it will stop because of friction. One place this law can be proved is in outer space where friction will not effect an object.

Answer 3

In the absence of any forces a mass will continue in a straight line at constant speed.

Creating an experiment to test this theory is difficult, as gravity, and its

effects on moving bodies on earth (namely friction) are always present.

Answer 4

Newton's law of motion dictates that no external forces be acting upon the object while it is in motion. Friction is an external force, therefore, it interferes with the law.
