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

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

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

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

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

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

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

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

Review of angular motion and equilibrium

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

We discuss systems in equilibrium and introduce the frictional force.

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

We introduce Newton's 3 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.

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

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

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]
