We review midterm #4 as well as chapters 1-8 on vectors, kinematics, projectile motion, Newton's laws, and work and energy

Review of Chapters 1-8

We review oscillation and simple harmonic motion, fluid mechanics, waves and sound.

Review of chapters 13-16

We look at wave effects for sound including interference and beat notes and the doppler shift caused by a moving listener or source.

Doppler Shift and Interference

We continue to look at mechanical waves, focusing on sound and hearing, specifically the decibel units for sound level.

Sound and Hearing

We introduce waves by considering solutions to the wave equations for propagation along a string.  We introduce the concepts of superposition and standing waves.

Mechanical Waves

We introduce the continuity equation for mass and volume flow rate and the Bernoulli equation for relating pressure, height and speed of fluid.

Fluid Dynamics

We introduce density, pressure and the buoyant force and derive Pascal's law for fluids.

Hydrostatics

We look at parameters of periodic motion.  Specifically we investigate simple harmonic motion and the pendulum.

Periodic Motion

Review of chapters 9-12

We look at Newton's law of gravitation and introduce the universal gravitational constant.  We also discuss escape velocity and black holes.

Gravitation

This is an enhanced audio podcast of  Dr. Beyersdorf's Physics 50 lectures at San Jose State University.  Episodes are recorded on Monday and Wednesday afternoons during the fall 2008 semester.

We discuss systems in equilibrium and introduce the frictional force.

Friction

We discuss how to use free body diagrams to solve problems involving forces.

Free Body Diagrams

Newton's Laws

We derive the centripetal acceleration of an object moving in circular motion and also discuss the concept of relative motion where an objects velocity is described in a different reference frame than that in which it is desired.

Circular Motion and Relative Velocity

We apply the equations of motion to problems in 2 dimensions.

Projectile Motion

We finish our introduction of vectors with an introduction of the dot product and the cross product.  We introduce displacement, velocity and acceleration as parameters of motion

Motion in 1 dimension

We look at dimensions and units of physical quantities and discuss the difference between scalars and vectors, as well as introduce vector addition. [note no audio due to technical issues]

Units, Scalars and Vectors

Dr. Beyersdorf does a *fantastic* job of explaining difficult physics concepts.  I highly recommend his whole series of lectures.

Dr. Beyersdorf is brilliant
