Newton`s Second Law of Motion
... Each component equation relates the forces on the object in that direction with the acceleration in that direction. A net force in the x direction will cause acceleration in the x direction. We will often just use the x and y directions in 2D. We will skip the vector notation when we are dealing wit ...

Moment of Inertia
... In applying Newton’s Second Law of Motion to rotational motion, it is known that the relation between torque and angular acceleration depends on both the mass and the distribution of that mass; this relationship is known as the moment of inertia. The moment of inertia for discrete distributions of m ...
