Answer:
A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F. The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.
Other units: dyne, pound-force, poundal, kip, kilopond
SI unit: newton (N)
In SI base units: kg·m/s2
Derivations from other quantities: F = m a
