Three point objects are located at various locations on a Cartesian coordinate system. Mass 1, with a mass of 1.1 kg, is located at (1.0,1.5) m. Mass 2, with a mass of 3.4 kg, is located at (3.0,1.0) m. Mass 3, with a mass of 1.3 kg, is...

Learn about protons, neutrons, and electrons in song format! A great way to boost classroom engagement when introducing new topics.

Our Sun releases a constant flow of charged particles & magnetic fields that creates a bubble in space (but not the soapy kind). Beyond the edge of this bubble is interstellar space, now home to the two Voyager...

The video is a lecture that explains the two features of a wave, namely wavelength and amplitude. It starts with a demonstration of a transverse wave and illustrates how the wave propagates while oscillating. The peaks and troughs of the...

Upon viewing the Rocks video series, students will be able to do the following: Define rock as a solid, naturally-occurring mixture of minerals. Define minerals as solids with a definite chemical composition and crystal structure....

The video is about covalent molecules, their properties and behavior. The video then goes on to discuss polymers, which are formed by the reaction of monomers with a C-C double bond. The video also discusses giant covalent structures,...
