Newton's Laws of Science



Newton's Laws of Science, are very important in the world today, because we need his laws to understand physics. Newton's first law states that, "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force." Newton's second law states that, "Acceleration is produced when a force acts on a mass. The greater the mass, (of the object being accelerated) the greater the amount of force needed (to accelerate the object). Newton's third law states that, "For every action there is an equal and opposite re-action." Some examples to represent what Newton's laws mean, The first laws means, that there is a natural tendency of object to keep on doing what they're doing. All objects resist changes in their state of motion will maintain this state of motion. His second law means that, everyone knows that the heavier object require more force to move the same distance as lighter objects. The third law means that, for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard. In my opinion, Newton's laws should be taught all around the world, because it is important to learn about the study of physics, and by learning about Newton's laws of Motion, you will have a better understanding of the study of physics. In conclusion, without Newton's laws the world would be a different place.
