A Classical & Relativistic Trip to a Black Hole

In this science activity, students read about the summer of 1971 when the Earth passed closer to Mars than it had since 1924. Students also learn about the retrograde motion of Mars as seen from Earth.

Introduce your young scholars to the concepts of circular motion, projectile motion, angular speed, simple harmonic motion, torque, center of mass, centripetal force, and Hooke's Law with a 86-slide presentation. The circular motion...

In this black hole worksheet, students use a given equation that relates the rate of matter falling into a black hole to the power emitted by the black hole to determine accreted mass.

In this black hole activity, students read about the black hole in the center of the Milky Way Galaxy called Sagittarius A and observe a Chandra image of the area where the black hole exists. Students solve two problems which include...

In this black hole worksheet, learners read about the three parts to a black hole including the Event horizon, the interior space and the singularity. Students solve five problems which involve using a given formula for the Schwarzschild...

In this black holes activity, students read about black holes and solve 3 problems where they calculate the Schwarschild radius of one, the number of grams/second a quasar luminosity implies for another and the number of suns per year a...

Put the fun in physics with ferrofluid! Aside from making cool shapes when it interacts with a magnet, what else can we learn from ferrofluid? A video from an extensive physics playlist examines the similarities between the...

The destructive power of black holes is enough to give any astrophysicist nightmares. No wonder the question arises as to whether a black hole can be destroyed. The narrator of a theoretical video explores the possibilities.

The prediction of gravitational waves rocked the scientific world, but it was many years before researchers tested the theory. See how Rainer Weiss applied his knowledge of sound waves to solve this impressive physics problem in an...

This PBS site is a classroom activity that takes a trip to a black hole. Students apply calculations on distance, velocity, acceleration, time, circular motion, density, and more.
