Learn how to calculate the kinetic energy of a gas molecule, describe the relationship between the temperature of a gas and the kinetic energy of atoms and molecule, and describe the distribution of speeds of molecules in a gas. The...

By the end of this section, you will be able to express the ideal gas law in terms of molecular mass and velocity; define thermal energy; calculate the kinetic energy of a gas molecule, given its temperature; describe the relationship...

[Free Registration/Login may be required to access all resource tools.] Students solve problems involving displacement, distance, velocity, speed, and acceleration, and then explore problems and graphs involving one-dimensional motion.

This applet allows the user to make observations about the relationship between speed and position and how both of these are affected by initial velocity and the incline on which the biker is traveling.

The necessity of gravitation to a circular orbit is discussed and equations for the orbital speed are derived from the law of universal gravitation. Binary systems in which two objects orbit about a center of mass are explained and...

Gain an understanding of average velocity and speed with this helpful reference tool. Provides a detailed definition and examples that enhance further explanation. Includes links to related topics.

Provides definitions, examples, and formulas for acceleration.

An activity that explores how two cylinders that are identical in shape and mass may travel down a hill differently due to how their mass is distributed. Learn how the distribution of mass in an object can affect its translational...
