... The concept of forces acting on a mass (one object) is intimately related to the concept of ENERGY production or storage. • A mass accelerated to a non-zero speed carries energy (mechanical) • A mass raised up carries energy (gravitational) • The mass of an atom in a molecule carries energy (chemica ...

Chapter 5 Work and Energy conclusion
... Energy can neither be created not destroyed, but can only be converted from one form to another. The result of a non-conservative force is often to remove mechanical energy and transform it into heat energy. Heat energy is the kinetic or vibrational energy of molecules. Examples of heat generation: ...

Center of mass
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero or the point where if a force is applied causes it to move in direction of force without rotation. The distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. Calculations in mechanics are often simplified when formulated with respect to the center of mass.In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics, the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass frame is an inertial frame in which the center of mass of a system is at rest with respect to the origin of the coordinate system.
