Cherokee blacksmith, soldier, and community leader Sequoyah ensured that his people’s language and culture would be preserved – by developing the Cherokee syllabary.

The Oxy Ride battery, developed by Matsushita, is a groundbreaking new generation battery that offers twice the performance of alkaline cells for high current applications. It can be used for a wide range of devices and is fully...

Projectile motion components demonstrated: constant velocity in x, free all in y.

In this video, the basics of electric circuits are discussed. The components of an electric circuit such as wires, batteries, resistors, capacitors, and switches are introduced with their respective symbols. The concept of electromotive...

Which will hit the ground first??!!???!?

If you know the speed of the car and height of a ball above a bucket, you can predict how far in front of the bucket to drop the ball so it will land in the bucket. It’s physics!

In this video, we will wrap up the FACTS SEARCH project and review the key concepts covered throughout the section. We will also download the final project, encompassing all the implemented features and functionalities.

In 1968, thousands of Latino students walked out of school in Los Angeles to protest against racial inequality in the classroom. Their collective action, known as the Blowouts, was a defining moment of the Chicano Movement.

In the mid 19th century a new political party, the Know Nothings, set the stage for xenophobia and nationalism to take root in American politics.

One of the worst miscarriages of justice in U.S. history, the Haymarket Affair, a labor action in support of an eight-hour working day, led to the unlawful executions of four Chicago residents.

This video will demonstrate how to mix paint with a paint brush as well as a palette knife. Pure vs. mixed colors will also be discussed.

This video will demonstrate how to print a collagraph plate without heavy-duty printmaking equipment.

In 1960, four Black students staged a sit-in in North Carolina to protest against racial segregation in the United States. The stools they sat on are the most visited artifacts at the International Civil Rights Center and Museum.

A humorous look at the topology of curved space.

What data is needed on the x and y axes of a graph that will have a straight, best-fit line with a slope equal to the resistivity of nichrome? We collect the data and answer this question.

A 1400 kg Prius uniformly accelerates from rest to 30 km/hr in 9.25 seconds and 42 meters. If an average force of drag of 8.0 N acts on the car, what is the average power developed by the engine in horsepower?

Why is there a “center seeking” centripetal acceleration? A step-by-step walk through of the answer to this question.

Example: A 321 g rubber, playground ball is dropped from a height of 77.8 cm above a force platform. The data for the force of impact collected at 1000 data points per second as a function of time is shown. Please determine a bunch of...

When the forces in a free body diagram don’t change students often think that Newton’s Second Law will yield the same results. This demonstration shows that is not true. This is a step-by-step analysis of tension force as a function of...

A 25 kg child is sitting on the edge of a merry-go-round. The merry-go-round has a mass of 255 kg and is rotating at 2.0 radians per second. The child crawls to the middle of the merry-go-round. What is the final angular speed of the...

What is the maximum linear speed a car can move over the top of a semi-circular hill without its tires lifting off the ground? The radius of the hill is 1.8 meters.

Rearranging Newton’s Second Law to derive the force of impact equation.

The #AngularMomentum of a #PointParticle moving at a constant velocity is shown to be constant.
