Deriving Displacement as a Function of Time, Acceleration and Initial Velocity
Deriving displacement as a function of time, constant acceleration and initial velocity

Plotting Projectile Displacement, Acceleration, and Velocity
Plotting projectile displacement, acceleration, and velocity as a function to change in time

Total Final Velocity for Projectile
Calculating the total final velocity for a projectile landing at a different altitude (mistake near end: I write 29.03 when it should be 26.03 m/s and the final total magnitude should be 26.55 m/s 78.7 degrees below horizontal

Using Calculus, you can efficiently find the optimal angle for a projectile. In this video we explain the formulas needed to efficiently calculate and find out the correct value.

Inclined Plane Force Components
Figuring out the components of the force due to gravity that are parallel and perpendicular to the surface of an inclined plane

Tension in an accelerating system and pie in the face
The second part to the complicated problem. We figure out the tension in the wire connecting the two masses. Then we figure our how much we need to accelerate a pie for it to safely reach a man's face.

Unit Vector Notation (part 2)
More on unit vector notation. Showing that adding the x and y components of two vectors is equivalent to adding the vectors visually using the head-to-tail method

Projectile Motion with Ordered Set Notation
Solving the second part to the projectile motion problem (with wind gust) using ordered set vector notation

Spring potential energy example (mistake in math)
A spring, a frozen loop-d-loop and more! (See if you can find the mistake I made and get the right answer!)

Harmonic Motion Part 2 (calculus)
We test whether Acos(wt) can describe the motion of the mass on a spring by substituting into the differential equation F=-kx

Thermodynamics (part 1)
Intuition of how gases generate pressure in a container and why pressure x volume is proportional to the combined kinetic energy of the molecules in the volume.

Electrostatics (part 1): Introduction to Charge and Coulomb's Law
Introduction to Charge and Coulomb's Law (video from May 2008 that I forgot to upload)

Proof (Advanced): Field from infinite plate (part 2)
We see that the infinite, uniformly charged plate generates a constant electric field (independent of the height above the plate)

Calculating dot and cross products with unit vector notation`
Calculating the dot and cross products when vectors are presented in their x, y, and z (or i,j, and k) components.

Viewing g as the value of Earth's Gravitational Field Near the Surface
Viewing g as the value of Earth's gravitational field near the surface rather than the acceleration due to gravity near Earth's surface for an object in freefall
