https://physics.info/motion/summary.shtml Summary Mechanics is the study of motion, forces, and energy. o Motion is the action of changing location or position. o A force is any interaction that causes a change in motion, shape, or energy. o A system possesses energy if it has the ability to do work. (Work is done when a force causes a change in the energy of a system.) Mechanics can be divided into sub-disciplines. o Kinematics is the branch of mechanics that deals with motion without regard to forces or energy. o Dynamics is the branch of mechanics that deals with motion and forces together. o Statics is the branch of mechanics that deals with forces in the absence of changes in motion or energy. o The work-energy theorem is the central principle of mechanics that relates forces and energy. o The conservation of energy is the central principle of science that deals with energy in all of its forms. o Kinetic energy is the term that refers to all forms of energy due to motion. There are several types of motion… o Translational motion results in a change of location. o Oscillatory motion is repetitive and fluctuates between two locations. o Rotational motion occurs when an object spins. o Random motion is unpredictable in practice or theory.
