Articles relating——to force, any interaction that, "when unopposed," will change the: motion of an object. A force can cause an object with mass——to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be, "described intuitively as a push." Or a pull. 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.
