Gravity is the only force that acts on a satellite. The force of gravity is the reason that satellites remain in orbit. It provides the centripetal force needed for the satellite to move in a circular motion. A satellite is acted upon by the force of gravity, which causes it to accelerate towards Earth. A satellite would move in a straight line path tangent to the Earth in the absence of gravity. In the absence of any forces, an object in motion, such as a satellite, would continue in motion with the same speed and in the same direction. This is known as the Law of Inertia. According to [Multimedia Physics Studios, http://www.glenbrook.k12.il.us/GBSSCI/PHYS/MMEDIA/vectors/sat.html], the force of gravity acts upon a high speed satellite to deviate its trajectory from a straight-line inertial path. A satellite is accelerating towards Earth due to the force of gravity.

The U.S.A Space Shuttle and International Space Station are both great examples of satellites orbiting Earth. This picture tells some facts about the International Space Station. The website gives more information about it. These were taken from the Kennedy Space Center in Cape Canavral in Florida.

{Katrina_aftermath.jpg} Bad tide
Spring and Neap Tides
Tides occur everyday, effected by the rotation of the Earth around the Sun and the Moon around the Earth. This causes the tides created to change where they occur. When the Sun and the Moon are aligned on the same side of the Earth, the tide caused their combined action is higher than normal and is called a spring tide. This reoccurs every 14 days, at new Moon or full Moon. When the Sun and the Moon form a right angle with the Earth, the gravitational forces of the Moon and Sun are in opposition and result in a weaker, intermediate tides called neap tides. These also take place every two weeks, at the first and third quarters of the Moon.

Because tides depend on the rotation of the Earth and that the Moon and the Earth around their common center of mass, the time of high tide and low tide at any point in time can be predicted. The solar time has a period of 12.41 hours (because of the monthly rotation of the Moon around the earth). The Moon's closest approach to the Earth is at perigee, and the farthest point in its orbit is at apogee, the mean between the two being about 238,857 miles (384,403 kilometers). When perigee coincides with the spring tides, they rise about 20 percent higher than normal.
