force is a quantity made up of?weight and speed?time and acceleration?magnitude and direction?mass and velocity?

  • science -

    Force is a characteristic of nature that tends to change the position or movement of objects. It is not made of anything. Force is an influence or effect of something else. Force as a quantity is not a concrete noun, but rather a measurable effect of influence on the motion or position of an object. Take the term Electromotive Force, for example, measured in volts. The EMF is not something one can see or make it up, it is a measurable tendency to move something (electrons), caused by the placement of other electrons.
