Forces What Is a Force? Forces represent the interaction of distinguishable objects. Specific forces: The weight W with magnitude W = m * g acts near Earth’s surface with g the gravitational acceleration. (m= mass) The normal force N is due to contact with a surface. It is directed perpendicular to the surface. The tension T is due to a taut‚ massless string. It is directed along the string. The external contact force Fext acts along the direction of the push.
