Do We Expand With the Universe?
The cat's out of the bag (or off the leash, in this case) regarding the expansion of the universe. In this intriguing episode, the narrator explains that space is expanding, not the objects within it. He also tells how expansion...

Study Jams! Gravity & Inertia
Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...

Minute Physics: What Is Dark Matter?
It's hard to explain stuff you can't see! But, this animated stick-figure drawing describes dark matter and how we know it exists. It likens the galaxy to a merry-go-round, holding the stars on their circular path. The one-minute...

Common Physics Misconceptions
Some commonly accepted concepts are not completely valid. In this video, the following ideas are thoroughly explained away:
Light cannot be effected by gravity
Velocity is additive
The earth appears to be flat
Not only is this an...

Minute Physics: What Is Gravity?
Gravity is thoroughly defined in this short, but weighty, featurette. The relationship of mass to force is incorporated, and the idea that gravity can also attract energy is introduced. In a flipped classroom situation, have learners...

Four Fundamental Forces, Scale of the Universe, Cosmology and Astronomy
Fundamental interactions are the non-contact ways that elementary particles interact. Sal describes electromagnetism, strong interaction, and weak interaction as being mediated by the exchange of gauge bosons between particles.

Why Gravity Gets So Strong Near Dense Objects, Cosmology and Astronomy
Sal uses Newtonian physics to explain the relationship between gravity and dense objects. He uses diagrams and relatively straightforward mathematics to demonstrate this concept.

Screaming Balloon - Sick Science! #161
Spangler uses balloons and hex nuts to demonstrate centripetal force and how to make a balloon "scream." He places a nut inside a balloon before blowing it up. Then, once the balloon is tied, he begins to spin the balloon around. A force...

Egg Drop Inertia Challenge - Cool Science Trick
This could get messy! Using a pie plate, a toilet paper roll, and a raw egg, Spangler aptly demonstrates one of Newton's classic laws: an object at rest will stay at rest until some force acts upon it. Sure enough, the demonstration...
