An analysis of the issac newton laws of motion

We are told most satellites orbit the Earth at altitudes of over km to avoid atmospheric drag, with a few circling in Medium Earth Orbit which goes up to 35,km! As you can see, all three objects above are in the seriously ferocious hot zone. The solar panels which adjorn these machines would barely function even if they could keep it together long enough. A British company found a drop of 1.

Galileo Galilei — and Johannes Kepler — Galileo pioneered the use of experimental method to discover mathematical laws governing the motion of terrestrial bodies.

Abstracting from the effects of friction, he proved that free bodies move horizontally with constant speed and fall vertically with constant acceleration. He also demonstrated that these two motions combine independently to produce parabolic trajectories.

Both the laws themselves and the method by which they were discovered were revolutionary achievements that opened the door to modern physics. At the same time, Kepler achieved a similar revolution in astronomy by discovering causal laws governing the motion of the planets around the sun.

His book, New Astronomy Based on Causescompleted the overthrow of the acausal, descriptive approach to astronomy that had impeded progress for so long.

Furthermore, some preliminary steps had been taken toward integrating the sciences of physics and astronomy. Earth was identified as one of the planets, and the telescope revealed that some celestial bodies have Earth-like characteristics: Our moon has mountains and valleys, Jupiter has moons, and the sun rotates.

How does one identify fundamental connections between phenomena that seem so radically different—for instance, between an apple falling or a pendulum bob swinging and a planet orbiting in an ellipse?

The key was to discover a mathematical theory relating motions to the forces that cause them.

This task was extraordinarily ambitious; in addition to the need for crucial new experiments and more accurate astronomical data, it required the development of new concepts and new mathematical methods.

When it was finally completed, the modern science of physics had been created—and celestial bodies took their place among its subjects, ruled by its laws. The Development of Dynamics Isaac Newton began with a problem that was simple enough to solve, yet complex enough to yield crucial new insights.

He began by analyzing the form of motion that the Greeks had regarded as perfect: Galileo had never grasped that bodies move with constant speed in a straight line in the absence of all external forces.

Kepler, on the other hand, had never grasped that any motion could occur in the absence of a force; he assumed that every motion is the result of an external push in the direction of the motion.

In his analysis of circular motion, Newton identified and rejected both of these errors. Prior to Newton, the case of the moon circling Earth was regarded as entirely different from the case of a hawk circling its prey.

Newton, however, ascended to a level of abstraction that treated these two phenomena as the same; his goal was to analyze circular motion as such, and apply what he found to any and all instances of it.

But he did not begin his analysis by considering the planets; he began with cases in which the cause of the motion is much easier to identify. He considered a weight attached to the end of a rope and swung around in a circle, and a ball rolling around in a circle inside a bowl.

In these cases, what is the cause of the circular motion?

For the weight, it is the tension in the rope; the man holding the rope must pull inward. If he lets go, the weight will no longer move in a circle, but will fly off horizontally in a straight line until the force of gravity pulls it to Earth.

For the ball in the bowl, the circular motion is caused by the inward push exerted by the surface of the bowl. If the ball escapes the bowl, then it too will initially fly off in a straight line. In both cases, the uniform circular motion of the body is sustained by a constant force directed toward the center of the circle.

In a notebook, Newton wrote an early version of what later became his first law of motion: Newton recognized that it was crucial to distinguish between the type of motion that results from a force and the type that can occur in the absence of force.

The concepts of motion used by Galileo were inadequate for this purpose.

However, something is essentially the same about the cases of acceleration studied by Galileo and the case of uniform circular motion: In both, a change in the motion results from an applied force on the body.Whether we are aware of them or not, Newton’s laws of motion are at play in nearly every physical action of our daily lives.

The 17th century was a time of intense religious feeling, and nowhere was that feeling more intense than in Great Britain. There a devout young man, Isaac Newton, was. The three laws proposed by Sir Isaac Newton concerning relations between force, motion, acceleration, mass, and inertia.

These laws form the basis of classical mechanics and were elemental in solidifying the concepts of force, mass, and inertia. ♦ Newton's first law states that a body at rest will remain at rest, and a body in motion will remain in motion with a constant velocity, unless. forces & Newton’s laws of motion.
