Introduction

Our understanding of the history of forces

In order to explore some of the thinking processes involved in the current dialogue between science and religion, I have imagined the following fable. The characters in my fable are modern-day versions of Galileo, Newton, and Leibniz. Also included is a lesser known historical figure, theologian Richard Bentley, with whom Newton corresponded. Galileo is pictured as a modern-day experimental physicist, performing increasingly precise experiments with falling bodies at the Leaning Tower of Pisa. I imagine him rapidly communicating his results by e-mail to Newton in Cambridge, who is contemporaneously developing his laws of motion and gravity. Of course,

Middle

Galileo died, and Newton was born, in 1642. That was a time of terrible religious persecution. During their lives, 50,000 women were accused of witchcraft and burned alive. Nineteen witch hangings in Salem were small potatoes beside that slaughter.

Meanwhile, Galileo's science drifted into conflict with the Church. For years he'd attacked the Church's Aristotelian science. He did all right until late in life. Only near the end did the sun-centered universe become too much for the Church.

And the real question isn't, "Why did Galileo get into trouble?" It is, "How did he stay out of trouble for so long?"

Early in the game, Galileo learned a secret.

Conclusion

Newton's Law of Motion tells us that "the worldline of an object with a given mass experiencing a constant force is a parabola (which is completely determined by knowing the mass and the force)". If it respects Galileo's democratic Principle of Relativity, then all inertial observers should see the worldline of that object to be the same parabola. Indeed, this too is true

Galileo wrote:

...Have the ship proceed with any speed you like, so long as the motion is uniform and not fluctuating this way and that. You will discover not the least change in all the effects named, nor could you tell from any of them whether the ship was moving or standing still.

    These are the gantry, operating console and a computer. Figure 1.2 shows the order in which the information passes. Figure 1.2 shows only basic components; other components will be explained later in the course of this report. Arguably, the most important part of a CT scanner is the gantry.

    Long jumper Bob Beamon benefited from the slight reduction in gravity and air resistance when he set the world record in Mexico City (short approach - short sprint). In higher altitude there is less air which is bad fro long distance runners as they have less oxygen in the air.

    He aimed to reject the view of Descartes, which was essentially Descartes's reworking of the Aristotelian ideas, that the colours we see around us occur because white light is modified when it interacts with the objects surface. Newton argued that different colours are inherently present in sunlight.

  2. Force and Newton's three Laws

    experience, let's start with the one that is due to the Earths rotation. With a bit of A2 wizardry we find that the centripetal acceleration at the equator is approximately 0.034 ms-2. This is way, way less than gravity, in fact its three hundred times smaller than the gravitational acceleration that you experience here on Earth.

    The acceleration record can be computer processed and integrated to obtain the velocity and displacement records. Acceleration, in physics, corresponds to the force applied to something that causes it to change its position or speed. It is the force you feel when a car accelerates from a stop sign; pushing you back into the car seat (it's a horizontal force).
