Any influence that tends to change the state of rest or the uniform motion in a straight line of a body. The action of an unbalanced or resultant force results in the acceleration of a body in the direction of action of the force, or it may, if the body is unable to move freely, result in its deformation (see Hooke's law). Force is a vector quantity, possessing both magnitude and direction; its si unit is the newton.
According to Newton’s second law of motion the magnitude of a resultant force is equal to the rate of change of momentum of the body on which it acts; the force F producing an acceleration a m s-2 on a body of mass m kilograms is therefore given by: F = ma See also Newton’s laws of motion.
1. Physical energy or intensity:; SYN. forcefulness, strength.
2. The physical influence that produces a change in a physical quantity
3. A powerful effect or influence:
4. Group of people willing to obey orders; SYN. personnel.
5. A group of people having the power of effective action
1. To do forcibly; exert force
2. To impose or thrust urgently, importunately, or inexorably; SYN. thrust.
3. To physical or metaphorical, as in; SYN. run, drive, ram.
In programming, to perform a particular action that would normally not occur. The term is most often used in the context of forcing data to be within a particular range of values—for example, forcing a divisor to be nonzero. See also cast.
