natural philosophy, physical science, physics - the science of matter and energy and their interactions

classical mechanics, Newtonian mechanics - the branch of mechanics based on Newton's laws of motion

fluid mechanics, hydraulics - study of the mechanics of fluids

pneumatics - the branch of mechanics that deals with the mechanical properties of gases

statics - the branch of mechanics concerned with forces in equilibrium

dynamics, kinetics - the branch of mechanics concerned with the forces that cause motions of bodies

kinematics - the branch of mechanics concerned with motion without reference to force or mass

aerodynamics, aeromechanics - the branch of mechanics that deals with the motion of gases (especially air) and their effects on bodies in the flow

reaction - (mechanics) the equal and opposite force that is produced when any force is applied to a body; "every action has an equal and opposite reaction"

rate of acceleration, jerk - (mechanics) the rate of change of velocity

carrying into action, carrying out, execution, performance - the act of performing; of doing something successfully; using knowledge as distinguished from merely possessing it; "they criticised his performance as mayor"; "experience generally improves performance"
