Blazars Are A Thing
Hank explains how quasars and blazars are both the same thing - just oriented differently in respect to us - and how that impacts the way we perceive them and how it also effects the ways we can study them.

Why Isn't "Zero G" the Same as "Zero Gravity"?
This Quick Question explains the difference between gravity and g-force, and how you can experience zero-g in space even when it’s not zero gravity!

Gravitational Mass
In this video Paul Andersen explains how the gravitational mass is a measure of the force on an object in a gravitational field. The gravitational mass is based on the amount of material in an object and can be measured to a standard kg...

TED-ED: The fundamentals of space-time: Part 3 - Andrew Pontzen and Tom Whyntie
In the first two lessons of this series on space-time, we've dealt with objects moving at constant speeds, with straight world lines, in space-time. But what happens when you throw gravity into the mix? In this third and final lesson,...

Free-Body Diagrams
In this video Paul Andersen explains how free-body diagrams can be used to solve kinematics problems. The only two parts of a free-body diagram are the object and all external forces acting on the object. Numerous situations are...

Equivalence Principle
In this video Paul Andersen explains how inertial mass and gravitational mass are equivalent. He shows you too simple methods for calculated individual inertial mass and gravitational mass. Albert Einstein used this principle to build...

Position vs. Time Graph - Part 2
Mr. Andersen shows you how to read a position vs. time graph to determine the velocity of an object. Objects that are accelerating are covered in this podcast. He also introduces the tangent line (or the magic pen).

TED-Ed: Would you weigh less in an elevator? - Carol Hedden
What happens when you jump in a moving elevator? Do you weigh more when you're going up and less when you're going down? Carol Hedden explores the relationship between gravity, weight, and relative motion, using a moving elevator to...

Is Gravity An Illusion?
Most of us take gravity as an assumed part of our living realities, but why? Basic physics introduces us to the concept of gravity from a Newtonian sense, but when you start factoring Einstein into an understanding of gravity, things get...

Interaction Forces
In this video Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant...

Friction: Crash Course Physics
Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it started moving? You might think it's all about weight, but actually it's about friction. Two kinds of friction!...

Kathryn Bouskill: The unforeseen consequences of a fast-paced world
Why does modern technology promise efficiency, but leave us constantly feeling pressed for time? Anthropologist Kathryn Bouskill explores the paradoxes of living in a fast-paced society and explains why we need to reconsider the...

Newtonian Gravity: Crash Course Physics
I'm sure you've all heard about Isaac Newton and that apple that fell on his head and how that was a huge deal to our understanding of gravity. Well... let's talk about that. In this episode of Crash Course Physics, Shini sits down to...

Astronaut Weightlessness Training
SciShow Space takes you behind the scenes of astronaut training, to show how crew members and their equipment are tested in microgravity, all while never having to leave Earth.

Torque
In this video Paul Andersen begins by discriminating between translation and rotational motion. He then explains how a torque is the product of the lever arm and the force perpendicular. The lever arm must be perpendicular to the axis of...

Newton's Second Law
In this video Paul Andersen explains how Newton's Second Law applies when a net force acts on a body. The net force vector and the acceleration vector will act in the same direction. If an object acts on another object in a system the...

Newton's Third Law
In this video Paul Andersen explains how Newton's Third Law applies to all objects. When an object applies a force to another object (Action) and equal and opposite force (Reaction) is applied to the original object. Several scenarios...

Speed, Velocity, and Acceleration
Mr. Andersen explains the basic quantities of motion. Demonstration videos and practice problems are also included. The difference between scalar and vector quantities is also discussed.

Vectors and 2D Motion: Crash Course Physics
Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of Vectors and Scalars so we can better understand how to figure out motion in 2 Dimensions. But what does that have to do...
