Angular Size and Velocity

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a...

Accelerate young physicists' learning with this collection of problem-solving worksheets. Starting off by teaching learners to identify the given information and variables in physics problems, this resource goes on to challenge them...

Written for a college physics course, this midterm examination deals with electric and magnetic fields. When taking this test, learners answer multiple choice questions, solve problems, and analyze a variety of attractive diagrams....

In this momentum worksheet, students use linear momentum to determine velocity and angular momentum to determine angular velocity. This worksheet has 1 problem to solve.

In this simple machines learning exercise, students review how simple machines are used to do work. Students understand the distance of resistance and apply this to answer 6 problems.

In this galaxies and fractions worksheet, students solve 8 problems involving the distances of galaxies from each other by using mixed fractions to solve each problem. They use the megaparsec as the unit of measurement.

For this stellar temperature of stars worksheet, students use a given formula that relates the stellar light output with the surface area and temperature of a star to solve 3 problems. Students find luminosities of different stars and...

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

The universe is 90 billion light years in diameter. How do scientists measure something so huge? Space Time explains the process as part of its larger Cosmology playlist. The video addresses the steps to solving the puzzle as well as how...
