Rates of Heat Transfer
On previous pages of this lesson, we have learned that heat is a form of energy transfer from a high temperature location to a low temperature location. The three main methods of…
Methods of Heat Transfer
If you have been following along since the beginning of this lesson, then you have been developing a progressively sophisticated understanding of temperature and heat. You should be developing a…
What is Heat?
Earlier in this lesson, five dictionary style definitions of temperature were given. They were: · The degree of hotness or coldness of a body or environment. · A measure of the warmth…
Thermometers as Speedometers
On the previous page of this lesson, temperature was defined as the reading on a thermometer. The process of calibrating a thermometer was explained and the variety of commonly used temperature scales…
Thermal Physics
Heat and Temperature Introduction to Thermal Physics Heat, energy and temperature pervade our lives. Just think about it. We give attention to hot and cold in deciding what we wear…
Energy Relationships for Satellites
The orbits of satellites about a central massive body can be described as either circular or elliptical. a satellite orbiting about the earth in circular motion is moving with a…
Weightlessness in Orbit
Astronauts who are orbiting the Earth often experience sensations of weightlessness. These sensations experienced by orbiting astronauts are the same sensations experienced by anyone who has been temporarily suspended above…
Mathematics of Satellite Motion
The motion of objects is governed by Newton's laws. The same simple laws that govern the motion of objects on earth also extend to the heavens to govern the motion of planets,…
Circular Motion Principles for Satellites
A satellite is any object that is orbiting the earth, sun or other massive body. Satellites can be categorized as natural satellites or man-made satellites. The moon, the planets and comets are examples…
Kepler’s Three Laws
Planetary and Satellite Motion In the early 1600s, Johannes Kepler proposed three laws of planetary motion. Kepler was able to summarize the carefully collected data of his mentor - Tycho Brahe -…
