Quantitative Definition Of Force Is Given By

The use of newton s second law as a definition of force has been disparaged in some of the more rigorous textbooks 3.

Quantitative definition of force is given by. Put another way force is any action that tends to maintain or alter the motion of a body or to distort it. The object shown below moves with constant velocity. Force is a quantitative description of an interaction that causes a change in an object s motion. Qualitative definition of force is given by a newton s law of gravitation b newton s first law of motion c newton s second law of motion d newton s third law of motion answer.

59 11 because it is. B newton s first law of motion question 15. Vec a is pre defined because vec a frac d vec v dt frac d 2 vec r dt 2 where vec v and vec r represent velocity vector and position vector respectively. Quantitative definition is of relating to or expressible in terms of quantity.

Force formulas are beneficial in finding out the force mass acceleration momentum velocity in any given problem. Brownian motion process on a simple application of newton s second law. Therefore force can be articulated as the rate of change of momentum. A quantitative definition of force can be based on some standard force just as distance is measured in units relative to a standard length.

F ma let v t denote the velocity of a colloidal particle of mass m it is assumed that read more. The relative units of force and mass then are fixed. Newton s first law tells us that a body that is not subjected to external agents a force will contin. Newton s second law of motion states that for a point mass vec f m vec a this is a law and not a definition.

With some justification newton s second law can be taken as a quantitative definition of mass by writing the law as an equality. According to newton s second law an acceleration is caused by a force which in this case is the tension in the string. So this law only makes sense if all the physical quantities appearing in this law are pre defined. Newton s first law is a statement about bodies not subjected to external influence that is a force.

Force isn t defined in newton s first law. In the centimeter gram second system of unit cgs unit force is expressed in dyne. Two forces are acting on the object. F p t dp dt.
