motion occurs when an object changes its position relative to a reference point.
Main application of rectilinear motion in the field of science is to find the motion, position and distance of an object. It can also be used to make comparison between the parameters of object in real field, relative velocity, relative motion and acceleration of an object can be determined. Thus, using the equations of rectilinear motion, one can take advantage in the field like factories of machinery where the terms like motion, acceleration, position of object are main functioning concern. Practically, to design something on the basis of motion, acceleration , etc , the equations of rectilinear motion are of great importance.
Yes. It always is when the motion is all in a straight line.
A body undergoes simple harmonic motion if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean. Provided the amplitude is small, a swing is an example of simple harmonic motion.
The motion along a straight line is known as rectilinear motion.
Motion is relative to an observer's frame of Reference.
Relative velocity/motion
Motion is always relative to the observers frame of reference. For example, if two people were standing facing each other, and a dog walked between them, one person would observe the dog's motion as going to the right, and the other person would observe the dog's motion as going to the left.
Two observers could measure a different speed for the same moving object if they are in relative motion to each other. This effect is known as the relativity of motion, where the perceived speed of an object can vary depending on the observer's position and movement. The observers may also be using different frames of reference or measurement techniques, leading to discrepancies in the calculated speed.
Motion is considered relative because how an object appears to be moving depends on the observer's frame of reference. Two observers moving at different speeds relative to each other will perceive the motion of an object differently. This concept is a fundamental principle of Einstein's theory of relativity.
Two different observers can measure a different speed for the same object due to relative motion. If the observers are moving at different speeds relative to the object, they will perceive its motion differently. This is described by the principle of relativity, which states that physical laws are the same for all observers in uniform motion.
The motion of an object looks different to observers in different frames of reference. This is due to the principles of relative motion, where an observer's perspective affects how they perceive the movement of an object. Different frames of reference can lead to variations in the perceived speed, direction, and trajectory of an object's motion.
The two postulates are the principle of relativity, which states that the laws of physics are the same for all observers in uniform motion, and the constancy of the speed of light, which states that the speed of light in a vacuum is the same for all observers regardless of the motion of the light source or the observer.
He is in motion relative to me, and he is at rest relative to his friends. There is no 'real' rest or 'real' motion. It's always measured relative to something else.
Motion is relative, meaning the perception of motion depends on the observer's frame of reference. When we describe motion as being "with respect to the observer," we are acknowledging that an observer's position and motion can affect how they perceive the motion of other objects. This is encapsulated in Galileo's principle of relativity, which states that the laws of physics are the same for all observers in uniform motion.
The observers motion in relation to what he observes.
It means the motion you measure for something depends on where you measure from. For example, You are on the sidewalk and measure the speed of a truck and its driver to be 60mph. But if you were in the truck and measured the speed of the driver it would be zero, because now, relative to you, the driver is not moving.
