mechanics

Physics

The study of the interactions between matter and the forces acting on it. Statics is broadly concerned with the action of forces when no change of momentum is concerned, while dynamics deals with cases in which there is a change of momentum. Kinematics is the study of the motion of bodies without reference to the forces affecting the motion. These classical sciences (see Newtonian mechanics; relativistic mechanics) are concerned with macroscopic bodies in the solid state, while fluid mechanics is the science of the interaction between forces and fluids.

Mathematics

The study of the behaviour of systems of particles or rigid bodies acted on by forces, whether in equilibrium or in motion. Classical mechanics is restricted to systems where Newton’s laws of motion are adequate—broadly speaking, any system where great gravity or speeds are not encountered, where the general and special theories of relativity apply. See also quantum theory.

Chemical Engineering

The study of the behaviour of bodies under the action of forces. Statics is the study of forces but without a change in momentum, whereas the study of dynamics concerns changes in momentum. The study of kinematics deals with the motion of bodies without reference to the forces that affect the motion. Newtonian mechanics is concerned with the bodies in the solid state, whereas fluid mechanics is concerned with the study of forces on fluids.
