CHAPTER
12 SUMMARY
Density and pressure: Density is mass per unit volume.
If a mass m of homogeneous material has volume V, its
density r is the ratio m>V. Specific gravity is the ratio of
the density of a material to the density of water. (See

Summary
vibrations of the engines of a particular type of airplane had just the right frequency to resonate with the natural frequencies of its wings. Large oscillations
built up, and occasionally the wings fell off.

9 SUMMARY
Rotational kinematics: When a rigid body rotates
about a stationary axis (usually called the z-axis),
the bodys position is described by an angular
coordinate u. The angular velocity vz is the time
derivative of u, and the angular accele

7 SUMMARY
Gravitational potential energy and elastic potential
energy: The work done on a particle by a constant
gravitational force can be represented as a change
in the gravitational potential energy, Ugrav = mgy.
This energy is a shared propert
CHAPTER
13 SUMMARY
Newtons law of gravitation: Any two particles with
masses m 1 and m 2 , a distance r apart, attract each other
with forces inversely proportional to r 2. These forces
form an actionreaction pair and obey Newtons third
law. When two or m

Torque: When a force F acts on a body, the torque of
that force with respect to a point O has a magnitude
given by the product of the force magnitude F and the

Picture the Problem: The rocking chair completes one full cycle or oscillation each time it returns back to its original position.
Strategy: The period is the time for one cycle. The frequency is the inverse of the period, or the n
