What exactly is "force" in physics?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
In physics, force is any interaction that changes an object's motion—either starting it, stopping it, speeding it up, slowing it down, or changing its direction. Measured in Newtons (N), force is defined by Newton's Second Law: F = m × a (force euals mass times acceleration). Force is a vector, meaning it has both magnitude and direction. Forces can be contact forces (like pushing) or field forces (like gravity acting at a distance).
