Relative position is a point established with reference to another position that is either moving or fixed. The coordinates of this point are usually true or bearing and are a distance away from the point of reference.
Relative position is essential in comparing one thing to another and in measuring the distance covered by an object. For instance, an athlete running from the starting line is said to cover a length that is relative to the point where he began the race. In this example, the starting point of the athlete is the reference point, and the point where he stops is the relative position. The position correlates to Einstein's theory of relativity that says everything in the universe is relative in nature.Learn More
Motion is relative to an observer or to an object. For example, a woman driving a car is not in motion relative to the car, but she is in motion relative to an observer standing on the side of the road.Full Answer >
Potential energy is defined as the energy possessed by a body due to its position or height above the surface of the Earth. Water stored in a dam has potential energy. This potential energy has the capacity to do work.Full Answer >
Force is any influence to an object which changes its motion, while motion itself is the change in position of an object in relation to is speed, location and acceleration. There cannot be movement without force used against an object to set it in motion.Full Answer >
Motion is defined as the action of changing position or location. Motion, along with force and energy, are concepts relevant to mechanics, a subject of physics. Within mechanics, there is a more specific field of study called kinematics, and this is the most basic level of mechanics.Full Answer >
