In contrast, an ocean going oil tanker travels at relatively low speeds but it too has a high momentum due to its very large mass. Both the bullet and the tanker can do a great deal of damage to other objects they hit, when their momentum is translated into force. Some materials or structures may only be deformed rather than moved when a force is applied. If it is insufficient to move the whole object but sufficient to move parts of it. In this way, the speeding bullet will dent a sheet of metal without moving it and the tanker might demolish part of a jetty.
Forces can change the shape of objects as well as change their motion.
In some circumstances it is possible to have forces acting on an object without producing either movement or changes in shape. The eight men in a tug of war team can exert an extremely large force as they pull on the rope. 1f this force were unopposed then they, and the rope, would move quite quickly backwards. However, when there is a team at the other end pulling with an equally large force, both teams and the rope remain stationary. A situation of balance or equilibrium is achieved where the forces of equal size acting in opposite directions effectively cancel each other out.
