Part IV IN WHICH we apply what we have learned so far in the context of specific common forces. We have now learned a lot and know all we need to tackle a wide variety of physics problems that involve 1-dimension motion. Now we will learn about some specific kinds of forces, several of which we’ve already discussed to some extent.

What you need to know and understand: Density – volume and mass. The force of gravity – gravitational field strength; weight; the acceleration due to gravity. Elastic forces – Hooke’s Law. Friction – a force that turns other forms of energy into heat. Frictional forces – viscous fluids. Frictional forces – air drag. Frictional forces – solids on solids (static and kinetic; friction coefficients).
Part V IN WHICH we see that what we have learned about linear motion applies to rotational motion, too. We also learn how to use rotational and linear (also known as translational motion) together to solve problems. There is a strong correspondence between motion of things moving along a straight line (translational motion) and things that move about an axis (rotational motion). Learning rotational motion simply adds a new dimension to the basics that we already know.
What you need to know and understand: Units of rotation. Relationship between tangential and angular quantities. Rotational velocity and the rotational version of the kinematic equations. Torque, Moment of Inertia, and the rotational version of Newton’s 2^nd Law of motion. General parallel between translational motion and rotational motion.
