    Concepts related to force include: thrust , which increases the velocity of an object; drag , which decreases the velocity of an object; and torque , which produces changes in rotational speed of an object. In an extended body, each part usually applies forces on the adjacent parts; the distribution of such forces through the body is the internal mechanical stress . Such internal mechanical stresses cause no acceleration of that body as the forces balance one another. Pressure , the distribution of many small forces applied over an area of a body, is a simple type of stress that if unbalanced can cause the body to accelerate. Stress usually causes deformation of solid materials, or flow in fluids .
