A position is a position of an object (whether it's a person, a ball, or a particle) at a particular point in time.
Displacement is the difference in position of an object from one point in time to another.
Distance is the total distance an object has traveled over a period of time.
In geometry and mechanics, the vector whose length is the shortest distance from the start point to the end point of a moving point P is called displacement.
A displacement is a number that describes how far apart an object or point is. In physics or everyday use, distance can refer to estimates based on physical length or other criteria.
Distance is the distance an object moves or changes direction. The position of an object within the reference frame is called its position

<span>At the end of World War I, President Wilson offended members of the United States Senate by travelling to Europe and opposing the League of Nations as well as opposing the views of Henry Cabot Lodge, thereby excluding them from the peace process. President Wilson was the President of the United States during the first world war. He tried to keep the USA out of the war but ultimately had to join the Allies against Germany in 1917. He also help broker a peace treaty with the USA joining the League of Nations. The US Congress vetoed this idea.</span>

Answer:
Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
AND
Examples:
Revolution of Earth around the sun.
Revolution of moon around the earth.
Velocity of a satellite around the earth.
Velocity of a car while driving.
Velocity of a ball when hitted with a bat.
Velocity of water coming from a tap.
Velocity of the train .
Characteristic velocity or , or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different propellants and propulsion systems.. Formula = ˙ is the characteristic velocity (e.g. m/s, ft/s) is the chamber pressure (e.g. Pa, psi)
Answer:
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. ... A mixture is made by simply mixing together elements and compounds. No new chemical bonds are formed.
