In this slow motion video for IPS Schools by Clayborn a ball is released on an inclined plane and accelerates due to the force of gravity. At the bottom of the first inclined plane to the beginning of the second inclined plane the ball stops its posi...tive acceleration by nearly maintaining its horizontal speed. On the second ramp the ball accelerates backwards down the slope, or loses speed to a point where it momentarily comes to rest. Therefore this video demonstrates POSITIVE ACCELERATION, ZERO ACCELERATION, AND NEGATIVE ACCELERATION or acceleration in the oposite direction. This video ignores friction and wind resistance and was intended for basic illustration of acceleration.

From DragonflyTV. Tyler and Aditya are roller coaster maniacs! The boys head to the Carnegie Science Center in Pittsburgh, to ride a roller coaster simulator. They took a measuring device called an accelerometer to find out which part of the simulati...on produced the most g-forces. Unfortunately, the simulator didn't produce the actual g's of a roller coaster. So they then took the accelerometers to a real roller coaster at a local amusement park and measured the number of g's on the accelerometer at different places along the ride. During the investigation, the boys learned that acceleration is speeding up, slowing down, or changing direction. They experienced the greatest g's at the bottom of the steep hill, when the direction changed quickly... almost 5 g's! The video/investigation is a great example of problem solving and the scientific method.

With the conventional wisdom of the Aristotelian world view, almost everyone could see that heavy bodies fell faster than lighter ones. Then along cam Galileo. His genius deduced that the distance a body has fallen at any instant is proportional to t...he square of the time spent falling. From that, speed and acceleration follow with the help of a mathematical tool called a derivative.

The function of mathematics in physical science. From a theoretical concept to a practical tool, the derivative helps to determine the instantaneous speed and acceleration of a falling body. Differentiation is developed further to calculate how any q...uantity changes in relation to another. The power rule, the product rule, the chain rule -- with a few simple rules, differentiating any function becomes a simple mechanical task.
