What\'s is a law of motion |
|
Answer» Law of motion is also known as the Newton\'s law of motion .,there are 3 laws of motion which is given by Newton:- 1.according to this law a body at rest will remain at rest and in motion will continue in a straight line 2. Rate of change of momentum of a body is directly proportional to the applied force and take place in direction in which the force act 3. according to this law of motion to every action there is an equal and opposite reaction .. hope this will help you . Sir Isaac Newton\'s three laws of motion describe the motion of massive bodies and how they interact. While Newton\'s laws may seem obvious to us today, more than three centuries ago they were considered revolutionary.Newton was one of the most influential scientists of all time. His ideas became the basis for modern physics. He built upon ideas put forth from the works of previous scientists including Galileo and Aristotle and was able to prove some ideas that had only been theories in the past. He studied optics, astronomy and math — he invented calculus. (German mathematician Gottfried Leibniz is also credited with developing it independently at about the same time.)\xa0Newton is perhaps best known for his work in studying gravity and the motion of planets. Urged on by astronomer Edmond Halley after admitting he had lost his proof of elliptical orbits a few years prior, Newton published his laws in 1687, in his seminal work "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy) in which he formalized the description of how massive bodies move under the influence of external forces.In formulating his three laws, Newton simplified his treatment of massive bodies by considering them to be mathematical points with no size or rotation. This allowed him to ignore factors such as friction, air resistance, temperature, material properties, etc., and concentrate on phenomena that can be described solely in terms of mass, length and time. Consequently, the three laws cannot be used to describe precisely the behavior of large rigid or deformable objects; however, in many cases they provide suitably accurate approximations.Newton\'s laws pertain to the motion of massive bodies in an\xa0inertial reference frame, sometimes called a\xa0Newtonian reference frame, although Newton himself never described such a reference frame. An inertial reference frame can be described as a 3-dimensional coordinate system that is either stationary or in uniform linear motion., i.e., it is not accelerating or rotating. He found that motion within such an inertial reference frame could be described by three simple laws.\xa0The\xa0First Law of Motion\xa0states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." This simply means that things cannot start, stop, or change direction all by themselves. It takes some force acting on them from the outside to cause such a change. This property of massive bodies to resist changes in their state of motion is sometimes called\xa0inertia.\xa0The\xa0Second Law of Motion\xa0describes what happens to a massive body when it is acted upon by an external force. It states, "The force acting on an object is equal to the mass of that object times its acceleration." This is written in mathematical form as\xa0F\xa0=\xa0ma, where\xa0F\xa0is force,\xa0m\xa0is mass, and\xa0a\xa0is acceleration. The bold letters indicate that force and acceleration are\xa0vector\xa0quantities, which means they have both magnitude and direction. The force can be a single force, or it can be the vector sum of more than one force, which is the net force after all the forces are combined.\xa0When a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force. However, if the object is already in motion, or if this situation is viewed from a moving reference frame, that body might appear to speed up, slow down, or change direction depending on the direction of the force and the directions that the object and reference frame are moving relative to each other.\xa0The\xa0Third Law of Motion\xa0states, "For every action, there is an equal and opposite reaction." This law describes what happens to a body when it exerts a force on another body. Forces always occur in pairs, so when one body pushes against another, the second body pushes back just as hard. For example, when you push a cart, the cart pushes back against you; when you pull on a rope, the rope pulls back against you; when gravity pulls you down against the ground, the ground pushes up against your feet; and when a rocket ignites its fuel behind it, the expanding exhaust gas pushes on the rocket causing it to accelerate.\xa0If one object is much, much more massive than the other, particularly in the case of the first object being anchored to the Earth, virtually all of the acceleration is imparted to the second object, and the acceleration of the first object can be safely ignored. For instance, if you were to throw a baseball to the west, you would not have to consider that you actually caused the rotation of the Earth to speed up ever so slightly while the ball was in the air. However, if you were standing on roller skates, and you threw a bowling ball forward, you would start moving backward at a noticeable speed.\xa0The three laws have been verified by countless experiments over the past three centuries, and they are still being widely used to this day to describe the kinds of objects and speeds that we encounter in everyday life. They form the foundation of what is now known as\xa0classical mechanics, which is the study of massive objects that are larger than the very small scales addressed by\xa0quantum mechanics\xa0and that are moving slower than the very high speeds addressed by\xa0relativistic mechanics.\xa0Additional resourcesHyperPhysics: Newton\'s LawsThe Physics Classroom: Newton\'s LawsNASA: Newton\'s Laws of MotionRECENT NEWSIs the Y chromosome dying out?Coronavirus news of the week (VIDEO)Lab confirms first case of coronavirus reinfection in the U.S.Ad Land Newton gave three laws of motion that describe the motion of bodies. These laws are known as Newton\'s Laws of motion.The first law of motion is stated as:\xa0An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.The second law of motion states that:\xa0the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.Newton\'s third law of motion states that:\xa0Whenever a body exerts a force on another body, the second body exerts an equal and opposite force on the first body |

Define osmosis.what happens when a plant cell is put into a hypertonic medium ?? |
|
Answer» Osmosis is the the process of solvent moving from lower concentration to higher concentration. It requires a semi permeable membrane. When the cell is placed in a hypertonic solution water does moves out of the cell andnit gets shrinked Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.When a\xa0plant cell is placed in\xa0a solution that is\xa0hypertonic\xa0relative\xa0to\xa0the cytoplasm, water moves out of the\xa0cell\xa0and the\xa0cell\xa0shrinks. |
