Topic: Motions and Forces
How and why do things move? What forces
do objects exert on each other, and what happens when they do? How
do bridges and skyscrapers support their heavy loads and stay
standing? What are the effects of gravity? Can sound travel through
liquids and solids? If so, how do sound waves behave? Explore
these questions and more in this collection of Motions and Forces
resources.
Resource Highlight
In this video adapted from NOVA scienceNOW, find out about the discovery of a new building material, the carbon nanotube, whose physical properties could theoretically enable the creation of a 22,000-mile elevator to space.
