Discussion the spectrum of mechanics

The general study of the relationships between motion, forces, and energy is called mechanics. It is a large field and its study is essential to the understanding of physics, which is why these chapters appear first. Mechanics can be divided into sub-disciplines by combining and recombining its different aspects. Three of these are given special names.
Motion is the action of changing location or position. The study of motion without regard to the forces or energies that may be involved is called kinematics. It is the simplest branch of mechanics. The branch of mechanics that deals with both motion and forces together is called dynamics and the study of forces in the absence of changes in motion or energy is called statics.

Science Notes: Measuring Matter, Force, and Energy

Matter, force, and energy are common terms that have scientific meanings close to the common use of the words. Matter is the stuff of which everything is composed, and force is something that is capable of changing the motion of an object. Energy is a property that tells us how much work we can get out of the object that possesses that energy. In keeping with the fact that science is based on measurements and observations, all of these entities are
