30 Mar Science Tuition – Newton’s Law
Do you feel that Science is a very bland and boring subject? Are you facing difficulties with the various topics and chapter of Science? Well, then we would like to invite you to try us once. Miracle Learning Centre is not your ordinary Science tuition center. One thing that you will never find here is boredom. Learning and acquiring new things needs energy, motivation, and enthusiasm. But if boredom takes over then how can anyone learn? The methods by which Science is taught at various schools and institutions makes it utterly boring to study. We want to change that. Our courses of secondary science tuition, primary science tuition, IP science tuition in Singapore are the most innovative, exciting and fun-filled all over Singapore.
In this science tuition lesson, we will be finding out more about Newton Law of Motion.
Newton’s Law is discovered by Sir Isaac Newton 300 years ago. It has worked in many areas of mathematics and physics. Newton’s law describes the body’s motion in terms of physics. In total there are three laws that affect the laws of motion. These three laws of motion are part of the field of physics, a type of science that people do not often think about in their everyday lives. But Newton’s laws are very important as it is related to almost everything that happens around us.
What are the three laws of motion?
Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This means if the object is at rest, it remains at rest unless a force is applied on it and if the object is moving, it will continue to move with the same speed in the same direction unless a force is applied on it.
Newton’s second law states that the relationship between an object’s mass m, its acceleration a, and the applied force F is F = ma. The force is directly proportional to the change of movement of the body. In this law, the direction of the force vector is the same as the direction of the acceleration vector.
Newton’s third law states that for every action (force) in nature there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. A real life example will be that when you are walking, you are actually pushing the earth and the earth pushes you back which then causes you to move.
