The third question was whether "applying" a force was different from applying an impulse. Do we define force and the magnitude of force in terms of the change of velocity of an object of mass 'm' to which a force F is applied (F = ma) i.e. a force is an influence that changes an object's velocity? Also, do we classify any accelerating mass as a 'force' i.e. force is also any accelerating mass? Note: If force is defined this way i.e. it is the product of the mass and acceleration, then to "apply" a force would be to create an influence on the object such that the mass 'm' undergoes an acceleration 'a'.

But that's just me __________________ Jerry (Got my results!) It is easier to protect your feet with slippers than to cover the earth with carpet. No one can go back and change a bad beginning; but anyone can start now and create a successful ending. If a problem can be solved, no need to worry about it. If it cannot be solved what is the use of worrying?
