Amusement Park Physics -- Roller Coaster
Roller Coaster For many people, there is only one reason to go to an amusement park: the roller coaster. Some people call it the "scream machine," with good reason. The history of this ride reflects a constant search for greater and more death-defying thrills. How does a roller coaster work? Once you're underway, different types of wheels help keep the ride smooth. Wooden or steel coaster: Does it make a difference?
Moment of inertia
Since the moment of inertia of an ordinary object involves a continuous distribution of mass at a continually varying distance from any rotation axis, the calculation of moments of inertia generally involves calculus, the discipline of mathematics which can handle such continuous variables. Since the moment of inertia of a point mass is defined by then the moment of inertia contribution by an infinitesmal mass element dm has the same form. Note that the differential element of moment of inertia dI must always be defined with respect to a specific rotation axis. Usually, the mass element dm will be expressed in terms of the geometry of the object, so that the integration can be carried out over the object as a whole (for example, over a long uniform rod). Having called this a general form, it is probably appropriate to point out that it is a general form only for axes which may be called "principal axes", a term which includes all axes of symmetry of objects.

How a Marble Maze Teaches Children Basic Physics
Budding engineers and scientists ages 5 and up can learn a lot about physics using a marble maze or marble run set. Marble maze sets come with lots of colorful pieces and assorted marbles to build a variety of mazes which include tunnels, ladders and bridges. There are unlimited possibilities in marble maze designs encouraging your child's creativity, imagination and thinking skills. Roller coasters are a great way for children to learn about basics physics such as speed, slope, friction and distance . Another excellent marble maze set to consider is the Original Classic Marble Run Set by Marble Run. For those who remember the "good ‘ole days" playing with glass marbles and wooden toys, you will love the Tedco Wooden Blocks and Marbles Maze Master Set. This set comes with 80 blocks, 20 marbles, playboard and a canvas bag to carry or store the set in.

The CD player has the job of finding and reading the data stored as bumps on the CD. Considering how small the bumps are, the CD player is an exceptionally precise piece of equipment. The drive consists of three fundamental components: A drive motor spins the disc.

Last edit date: 2012-12-07 Introduction Did you know that the screen of an Apple® iPhoneTM can change between portrait and landscape mode simply by turning it? Accelerometers are used in several applications. There are two types of accelerometers, single-axis (vertical or horizontal) and multi-axis.
The period of a satellite
The period of a satellite Added by David Fairhurst on Feb 6, 2008 An interactive animation showing a satellite orbiting the Earth. Move the slider to change the height of the satellite's orbit and observe the effect this has on the period of the orbit. This resource is from the unit Satellites and Orbits which is part of Absorb Physics. The full Absorb Physics course normally sells for £400 - but you can get it free for your school!

Terminal velocity of a skydiver
Terminal velocity of a skydiver Added by David Fairhurst on Feb 6, 2008 An interactive animation illustrating the terminal velocity of a skydiver. Terminal velocity is reached when the downward force of gravity is balanced by the upward force due to air resistance. This resource is from the unit Friction which is part of Absorb Physics.

Mass of the Earth
topic index | author index | special index As we all learned in grade school, the Earth is the third planet from the Sun. The planet Earth is only a tiny part of the universe, but it is the home of human beings and all known life in it. Animals, plants and other organisms live almost everywhere on Earth's surface. It ranks fifth in size, and its mass is found to be about 5.98 × 1024 kg. The mass of the Earth may be determined using Newton's law of gravitation. F = Gm1m2/r2 = ma Gm/r2 = g m = gr2/G m = (9.8 m/s2)(6.37 × 106 m)2/(6.673 × 10-11 Nm2/kg2) m = 5.96 × 1024 kg The Earth gains mass each day, as a result of incoming debris from space. Samantha Dong -- 2002 Earth, the third planet from the sun, is one of the most unique celestial bodies in our solar system. In approximately 230 BC, the Greek mathematian, Eratosthenes calulated the radius of the Earth. Sir Isaac Newton greatly contributed to the study of physics and therefore, his efforts determined the mass of the Earth. F = GmM/r2
