I'm am quite familiar with atmospheric pressure, but I did learn about plasma and Bernoulli's principle. It is quite and interesting concept.

I have learned about buoyancy before, but it was a nice review. I especially liked the different and more in-depth explanation of Pascal's principle. I also got to learn about how capillarity works.

In this lecture, I learned that to get density, you must divide mass by volume

In this lecture, I learned where the nucleus is located- in the center of an atom

Thank you for the lecture. It was nice to see and learn how we have measured escape speeds on various planets and bodies within the Solar System.

We went over a little bit already on the parabola and projectile motion in a previous lecture, but it's nice to see it in more detail. However, it was very interesting to learn about how the parabola is actually a part of an ellipse that extends within the Earth. It was great to learn about ellipses and satellites in general.

Einstein's Theory of Gravitation is very interesting to learn about as he proposes that distortions of space-time is created by mass and energy. The trampoline metaphor definitely helped.

I found this lesson very informative. It was very interesting to learn how spring tide and neap tide is the product of the gravitational force of the moon and sun. I knew what they were, but not why that was.

This was a great expansion on rotational motion. I was able to learn the difference between the difference between centrifugal and centripetal force.

This lecture taught me a great deal about the many things that can go into rotational motion. This includes torque and rotational inertia.

This lecture was very useful. Especially the concept of machines introduced into this physics lesson, it provides change in the conservation of energy and introduces efficiency.

This lecture was very useful in refreshing me and relearning the concept of work and power as well as the concept of the work-energy theorem.

I was able to get a better understanding of impulse and learn about the relationship between momentum and impulse.

I learned the relationship of the horizontal and vertical vectors that resulted in the resultant vector.

This lesson taught me why guns need to be heavy.

In this lecture, I learned that mass is different from weight.

in this lecture, I learned that if you multiple the average speed and the time traveled, you can get the total distance covered by an object.

I learned that for every action there is an equal and opposite reaction

I was able to learn more on the difference between mass and weight. The correlation between acceleration and mass following Newton's Second Law of Motion.

I managed to review and relearn a little more on equations for free fall and a little sneak peak of velocity when traveling in a parabola.

in this lecture i learned that there is still a lot to learn about matter

In this lecture I learned the equations for acceleration, velocity, and free fall velocity and distance.

In this lecture, I learned that matter is still unexplained.

In this lecture, I learned the definition of velocity and the difference from acceleration.

In this module I learned that we do not really understand matter.

In this module I learn the formula d=1/2gt^2

In this lecture, I learned that inertia is applied in our lives constantly. Our bodies are always moving and resisting the change in motion.

In this lecture, I learned that the scientific method is not always used by scientist. Also, a theory is just a large amount of information but could be false.

In this lecture I learned that an example of a scientific method is The Big Bang Theory or the theory of evolution.

I learned that a moving object can be in equilibrium when the force applied and the force of friction are equal each other. This creates a linear equilibrium with a net force of 0.

I learned about the equilibrium rule in this lecture

In this lecture I learned what the equilibrium rule is.

In this lecture I learned the difference between theories and laws.

Thank you for the lecture! I learned all these concepts before, but it has been quite a long time so it was a nice review. I especially enjoyed the explanation of the concept of weight affecting speed being correct in both Aristotle's and Galileo's theory. However, the thing I learned most was the concept of relative motion like with the examples you gave of the moving Earth. It was very interesting.

I usually think that the terms given within this lecture are very straightforward, but I do find that the examples you give to explain them are great, especially your explanation on the complexities of theories, facts, and laws. Afterall, what we have establish may not necessarily be the truth and applicable in all situations.

Whaaat!

I learned that the photoelectric effect is emission of electrons from a metal surface when light shines on it.

I learned that phosphorescence differs from fluorescence by a delay between excitation and de-excitation

I learned that the microworld is quantum theory.

I learned that excition is the process of moving an electron to a different energy level.

In this lecture I learned that quantum physics plays a big role in the photography phenomenon and is utilized in biopsy tests.

In this lecture I learned that white light is made up of different wave colors and a laser is made up of one coherent wave color and same wave lengths.

In this lecture I learned that Albert Einstein got his Nobel prize for explaining the photoelectric effect in the context of quantum mechanics!

Planck’s Constant represents the energy of the photon being measured which is equal to the frequency of the light wave. Planck’s Constant Equation is characterized as E 🟰 h ✖️ f

To first understand excitation we must understand the further an electron is from an atom’s nucleus , the greater its potential energy. While electrons typically remain in their prescribed energy level that orbits a nucleus, a bombarding free electron can collide with a bounded electron, thus raising it to a higher energy level, which then puts that electron in a state of excitation.

Dispersion is phenomena where light rays, depending on their frequencies, get “dispersed” or separated when traveling through a medium.

I learned that Planck's constant is fundamental, h, which relates the energy of light quanta to their frequency.

I learned that a spectroscope breaks the light from a single material into its component colors the way a prism splits white light into a rainbow.

I learned that the emission spectrum is the distribution of wavelengths in the light from a luminous source.

In this lecture I learned that the peak frequency is proportional to the temperature. So, the higher you heat something the greater the average peak frequency.
