How do we define the system? The surroundings? In this video, we explore this along with energy transfer between system and surroundings in the forms of heat and work. We also do a sample calculation of total energy (E = q + w).

Review of the Universal Gravitation topics covered in the AP Physics 1 curriculum.

Physical Differentials (2 of 2): Coulombic Transformations

We've already learned about different types of chemical bonds, including covalent bonds. But now that we know about enthalpy, and orbitals, and some other concepts, let's revisit the covalent bond and dig a little deeper.

The force of gravity and the gravitational potential energy between an object and a planet is derived and graphed, inside and outside the planet.

In this video, we discuss the conceptual aspects of the quantum mechanics model, Particle-in-a-Box (also called the Infinite Potential Well model): Wavefunctions and Energy Eigenvalues. NEXT VIDEO: Particle-in-a-Box Example Problems

Tic tacs have the strangest behavior when you bounce them on a very hard surface. What is going on?! Find out the physics.

In this video, the teacher explains the concepts of kinetic and potential energy, specifically focusing on gravitational potential energy. They use examples and a simulator to demonstrate how potential energy is converted into kinetic...

Catapults were mighty handy for pirates in the golden age of piracy (during the 17th century). And medieval knights used them centuries earlier for taking down massive castle walls. Even Greeks and Romans used catapults about 2,000 years...

Voltage explained. What is voltage and what does it do? In this video we discuss how it work and its purpose to understand how electricity works. We'll look at voltage for both alternating current and direct current starting off very...

A discussion of electrical voltage, and how to understand it.

Here I pool the results of all the previous videos together to get a fascinating result - the conservation of Mechanical Energy

For this one we will want to recall some of the rules about doing E2 on a cyclohexane ring, as well as the relative stabilities of cyclohexane chairs. Combining concepts! Predicting kinetics!

Now you're really getting advanced with your building skills. Check out this pendulum. It's a good thing we know about potential energy and kinetic energy, because that will allow us to calculate the velocity of the pendulum at any...

For this one we need to understand what the different parameters on an energy diagram correspond to. Check out my tutorial on this subject in the general chemistry playlist if it seems fuzzy!

For this one we need to understand the stereospecificity of hydrogenation over platinum metal, stereochemical relationships, and the relative stability of cyclohexane chair conformations.

Look at this nifty ramp you made! Let's roll some stuff off of it, shall we? Good thing we know all about potential energy and kinetic energy, because that will allow us to calculate all kinds of things, like the velocity of the ball at...

You're a mischievous little physicist, aren't you? Well I guess there's no harm in projecting a toy into the air, especially if it's part of your scientific research. Given a spring constant and some other information, how high will this...

Mechanical energy problem 4 part 2

Spin that sigma bond and what do you get? Draw the Newman projections and find out! Watch out for pesky gauche interactions.

Particle in a Finite Potential Well: Quantum Tunneling
