3. Isaac Newton Newton was an English mathematician, physicist, astronomer, alchemist, theologian, and author widely recognized as one of the greatest mathematicians and physicists of all time and among the most influential scientists.

4. Newton’s Law of Motion Each law of motion that Newton developed has significant mathematical and physical interpretations that are needed to understand the motion of objects in our universe. The applications of these laws of motion are truly limitless. Essentially, these laws define the means by which motion changes, specifically the way in which those changes in motion are related to force and mass.

5. Newton’s First Law of Motion “ Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. “

6. Newton’s Second Law of Motion “ A force causes only a change in velocity (an acceleration); it does not maintain the velocity. “

7. Newton’s Third Law of Motion “ For every action there is an equal and opposite reaction. “

8. ACTION AT A DISTANCE FORCES

9. Mass and Weight Mass is a measure of the amount of material in an object, weight is the gravitational force acting on a body (although for trading purposes it is taken to mean the same as mass), force is a measure of the interaction between bodies and load usually means the force exerted on a surface or body.

10. MASS Mass is a scientific measure of the amount of matter an object is made up of. No matter where you are at given moment in time, mass is constant. So, whether you are walking to the shop to stock up on groceries or bouncing around on the moon, your mass is the same. Obviously, if you are on a diet that is not the answer you want to hear but do not panic we will get to the all-important definition of weight shortly.

11. Some other key points about mass: 1. Mass is indestructible. As you’ve seen above, no matter where you are universe your mass will never change.
2. Mass can never be zero. What we mean by this is that everything in the universe has mass. If it didn’t it simply wouldn’t exist . 3. Mass is not related to gravity, centrifugal force, etc. and these forces have no effect whatsoever on your mass.
4. Mass is commonly measured in kilograms and grams.

12. WEIGHT Weight is a form of measurement that is dependent on gravity and, unlike mass, yout weight can vary depending on where you are in the universe. Weight is a pretty important measure not only to dieters the world over but also to the scientists and egg heads who design things like space shuttles and boats – opposite end of the spectrum, but it is all about perspective. Formula: Weight (W) = Mass (M) multiplied by gravitational acceleration (g). (W = mg)

13. Application Of Newton’s law of motion

14. 1. An apple falling to the ground must be under the influence of a force, according to his second law. That force is gravity, which causes the apple to accelerate toward Earth's center. 2 Newton reasoned that the moon might be under the influence of Earth's gravity as well, but he had to explain why the moon did not fall into Earth. Unlike the falling apple, it moved parallel to Earth’s surface.

15. 3. What if, he wondered, the moon moved about the earth in the same way as astone whirled around at the end of a string? If the holder of the string let go-and therefore stopped applying a force the stone would obey the law of inertia and continue traveling in a straight line, like a tangent extending from the circumferencer of the circle. 4. But if the holder of the string did not let go, the stone would travel in a circular path, like the face of a clock. In one instant, the stone would be at 12 o'clock in the next, it would be at 3 o'clock. A force is required to pull the stone inward so it continues its circular path or orbit. The force comes from the holder of the string.

16. 5. Next, Newton reasoned that the moon orbiting Earth was the same as the stone whirling around on its string. Earth behaved as the holder of the string, exerting an inward-directed force on the moon. This force was balanced by the moon's inertia which tried to keep the moon moving in a straight-line tangent to the circular path. 6. Finally, Newton extended this line of reasoning to any of the planets revolving around the sun. Each planet has inertial motion balanced by a gravitational attraction coming from the center of the sun.
