... Inertia has to do with the tendency of all objects to keep doing what they are already doing. Newton’s first law says that objects will keep doing what they are already doing unless an unbalanced force acts on them. So, they both have to do with inertia. 2. How are mass and inertia related?

... Later, the proportionality was made into an equation a = F/m, or F = ma and force was defined as more than a push or pull. The units for force are taken from ma, kgm/s2, which are called Newtons, in honor of Isaac Newton. For example, a net force of 1 N acting on a 1 kg object causes it to accele ...

2. Newton`s Second Law of Motion [ F=ma]
... When a net or unbalanced force acts upon an object, its rest or uniform motion is changed and the object must accelerate. Newton’s 2nd law states that the magnitude of the acceleration is directly proportional to the magnitude of the net force (if you double the net force, you double the amount of ...

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.
