Describes the logic behind the development of Newton's law of universal gravitation. Beginning with Johannes Kepler and his three laws of planetary motion, content walks the reader through Newton's thought process and development of this...

A handy resource that gives an overview of equations and definitions pertinent to an introductory, college-level physics course, with two of its three sections focusing on motion-related topics and principles.

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...

Examples of conic sections are given and the equation for their standard form is also given.

Students will enjoy this data collection and class analysis experiment involving the time it takes for a hand squeeze to travel around a circle of people. From organizing the activity to collecting the data to making a table and graphing...

This page offers a variety of math center ideas for general math and geometry. Instructions on setting up the center are not provided for most ideas, however, those lacking instructions are pretty self-evident.

2 OF 2 FOR ADDITIONAL TOPICS IN MATH. Students will use the coordinate plane and equations of lines and circles to describe figures; create the equation of a circle given the figure or use the structure of a given equation to determine a...

This task has two separate goals: the first is to solve a pair of equations, one quadratic and the other linear. The second goal is to observe that a point that lies on a circle gives rise to a Pythagorean triple. Aligns with A-REI.C.7.

In the July 2013 issue of United Airlines' Hemisphere Magazine, a pilot responded to a question about how far in the distance he could see at different altitudes. The solution involved right triangles, lines of tangency to a circle, and...

Students can investigate the graphs of conic sections in standard form. Cirlce, ellipse, and hyperbola graphs are included.

Students investigate how to graph a wide variety of equations and functions. Topics explored are lines, rational functions, parabolas, ellipses, and transformations. Class notes, definitions, and examples with detailed solutions are...

Learn about the tangent definition in geometry, tangent geometry, tangent to a circle, tangent line equation. Check-out the solved examples for better understanding and try your hand at the tangent line calculator or solving a few...

Understand the design criteria that should be met by any gear design to meet the American Gear Manufacturers Association standards. The accompanying video discusses how the design inputs (power transmitted, space constraints, and...

MathWorld offers a definition of the apothem of a circle as well as an illustration is provided on this page. An equation is also provided to calculate the apothem of a circle given the radius and the sagitta.
