Working in Space

Who knew F=MA could determine the force of a free-falling elevator? Give your class this set of thirteen word problems for practice determining force, mass, and acceleration of everyday objects. One question introduces an object in...

In 1895, Konstantin Tiolkovsky proposed the concept of a space elevator. It's now over 100 years later and scientists working toward the concept still aren't sure it is possible. The video explains the concept, the benefit, and the many...

Does space have its own gravity? And, if so, why do astronauts just float around in the space station? Science sleuths examine the forces acting upon astronauts in the International Space Station with help from the narrator. He...

NASA tracks around 20,000 pieces of debris orbiting Earth. The garbage humans leave in space cause problems for space exploration, satellites, and communication. One group of scientists hopes to clean up the junk and make this planet...

Would an evil mastermind trying to take over the universe use explosives in space? A video that is part of a larger series approaches this question with physics of course! She explains the role of the atmosphere, the properties of waves,...

What makes a clock tick or a bulb light up? The concept of work is explained to a backdrop of clever animation. Physics fans learn that the amount of work equals the product of the force and distance, and that the rate equals the amount...

Here's a force to be reckoned with in the physics classroom! Scholars discover the movements associated with tension, compression, and other common forces through a hands-on simulation. Pupils pull, push, and twist their way through each...

Develop an understanding of the relationship between energy, work, and power. The video instructor explains the meaning of each and describes how they work together. He then provides an example that applies the formulas for both work and...

Looking for a quick way to supercharge your electricity and magnetism unit? Assign a very responsive interactive designed to illustrate the relationship between charge, electric field, and the resulting forces. Learners experiment with...

Why are gym walls padded and cars required to have air bags? Scholars observe two similar situations, such as those listed above, with only one variable altered. They identify the different variable and determine how the variation...
