Newton First Law of motion states that "A body continues in its state of rest or of uniform motion in a straight line until/unless an external force is applied upon it" Why is it so? "Inertia is the property of a body to resist any change in its state of rest or of uniform motion in a straight line" Newton's first law of motion is also therefore known as law of inertia because of the inertia the body will remain in its initial state forever. And mass is the measure of the inertia of a body.
No, the orbits of planets are not perfectly circular but are elliptical in shape. The path of planets around the Sun can be best described using Kepler's laws of planetary motion, which state that planets move in elliptical paths with the Sun at one of the foci of the ellipse.
Newton had accomplished a lot in his life, He had devoted much of his work towards alchemy, theology and history, In 1669, Sir Isaac newton built the first reflecting telescope, During his life he was involved in the development of the calculus, It was then newton had struck the Laws of Motion and the Law of Gravitation. 1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. 2. The net force on a body is equal to its mass multiplied by its acceleration. 3. For every action there is an equal and opposite reaction.
A satellite like the space shuttle is in a state of freefall, which means that it is continuously accelerating towards Earth due to gravity, but its forward velocity keeps it in orbit, creating an elliptical path around the planet. This motion can be described as a projectile in a non-accelerated or constant velocity state within the orbital path.
Planets follow elliptical orbits due to the gravitational pull of the sun, which causes them to move in an elliptical path rather than a perfect circle. This is described by Kepler's laws of planetary motion, which state that planets move in elliptical orbits with the sun at one of the foci.
Johannes Kepler (1571-1630), a German who travelled to Prague to become the assistant of Brahe, was studying the orbit of Mars and while examining that data discovered the Laws of Planetary Motion which state an elliptical orbit rather than a circular one.
Laws of planetary motion.
Kepler's 1st law of planetary motion state that Each planet moves in an elliptical orbit with the sun at one focus.
The cubes of the average distances of the planets from the sun is proportional to the squares of their periods.
The three laws of planetary motion formulated by Johannes Kepler state: Planets move in elliptical orbits with the Sun at one focus. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
The tendency of a body to maintain its state of motion is called inertia. This principle is described by Newton's First Law of Motion.
Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This means that an object will not change its state of motion unless a force is applied to it.
This tendency is called inertia, as described by Newton's First Law of Motion. Inertia is the resistance of an object to changes in its state of motion.
Newton's First Law Of Motion States: "Every body continues in its state of rest of of uniform motion in a straight line unless it is compelled to change that state by an external force impressed upon it"
This statement is known as Newton's first law of motion, also called the law of inertia. It means that an object will continue to stay at rest or move at a constant velocity unless acted upon by an external force to change its state. In other words, an object will maintain its current state of motion (or lack of motion) unless a force acts upon it.
The state in which there is no change in a body's motion is called "inertia." Inertia refers to an object's tendency to resist changes in its motion unless acted upon by an external force. It is a fundamental principle in physics described by Newton's First Law of Motion.
The natural state of motion is to continue moving in a straight line at a constant speed unless acted upon by an external force. This concept is known as inertia and is described by Newton's First Law of Motion.
