Can a moving object be selected as a reference object?
Any moving object can be redefined as a frame of reference at rest, from which all other moving frames can be measured. That's a fundamental precept of Relativity. It's motion is defined only in relation to some other object from which the motion is measured, so reselection as the rest frame is necessary, but once established as a rest frame, it is (for the purpose of measurement) no longer considered to be in motion. Since everything is moving in relation to everything else, any frame can be selected as the frame of reference at rest, with all other motion measured relative to it.
Is earth's surface currently moving away from the rest of the planet?
No. The surface of the earth is held to the planet by gravity. However parts of the surface move relative one to another - this is called plate tectonics.
Define rest in physics?
An object is said to be at rest if it does not change its position with respect to its surroundings.Surroundings are the places in it's neighbourhood where various objects are present.====================Opinion #2:"Rest" means that the motion of the object you're describing is exactly identicalin every way to the motion of you, the observer who is observing it.
Can a body be regarded in the state of rest as well as in motion at the same time?
The lady reading the motionless book in her lap, while she sits in her comfortable seat,which is in Row 23 of the airliner taking her to visit her grandchildren across the country,and is just now cruising at 420 knots at an altitude of 35,000 feet.-- The book is motionless relative to the lady's lap.-- The book and the lady are both motionless relative to the seat.-- The book, the lady, and the seat are all motionless relative to the airplane.-- All four of them are moving at about 485 miles per hour relative to the grass on the ground.None of these states of motion is the 'real' one, and all of them are. There's no such thingas the 'real' one. Every state of motion is relative to something else.
Give an example in which rest and motion occurs at same time?
A guy/girl driving a car is a good example of this question because when guy/girl is driving his/her body is in rest but also in motion because of the movement of car hope its the answer of the question
Which is at rest relative to the seated passenger in a moving car?
The seated passenger in a moving car is at rest relative to the car's interior.
What is at rest relative to a seated passsenger in a moving car?
Everything else in the car that is not itself rotating etc. is at rest relative to the passenger -- the seats, car body, dashboard, windows, etc, "At rest" is in this case just another way to say "moving at the same velocity."
A passenger in the rear car of a train moving at a steady speed is at rest relative to?
the passenger will be at rest relative to the rear car of the train, as they are both moving at the same speed and direction.
A passenger in the rear seat of a car moving at a steady speed is at rest relative to what?
The passenger in the rear seat of a car moving at a steady speed is at rest relative to the car itself. This is because the passenger is moving with the same velocity as the car, so they appear to be at rest relative to each other.
In which situation can you be at rest and moving at the same time.?
One situation where you can be at rest and moving at the same time is when you are inside a moving vehicle. While you are stationary relative to the vehicle (at rest), you are moving relative to an observer outside the vehicle.
A passenger in the rear seat of a car moving at a steady speed is at rest relative to?
The passenger in the rear seat of a car moving at a steady speed is at rest relative to the car itself. This is because the passenger and the car are both moving together at the same speed in the same direction, so from the perspective of the car, the passenger appears to be at rest.
Examples of relation between motion and rest?
Motion and rest are relative concepts in physics, meaning that an object can be in motion or at rest depending on the frame of reference. For example, a person seated in a moving train is at rest relative to the train but in motion relative to an observer outside the train. This demonstrates how motion and rest are interconnected depending on the chosen point of view.
In which situation can you be at rest and moving at the same time?
You can be at rest and moving at the same time in a rotating reference frame. For example, if you are sitting in a car that is moving at a constant speed on a circular track, you are at rest relative to the car but moving in a circle relative to an observer on the ground.
Which situation can you be at rest and moving at the same time?
Being at rest is a relative term. Relative to earth we are at rest when we are sitting down. However, you are moving because the earth is moving its orbit around the sun.
In which situation can be at rest and moving at the same time?
Being at rest is a relative term. Relative to earth we are at rest when we are sitting down. However, you are moving because the earth is moving its orbit around the sun.
Is the pen at rest in motion?
The pen is at rest as long as it is not moving relative to its surroundings. If the pen is stationary, it is considered to be at rest.
Prove that rest and motion are relative terms?
Actually sitting on the earth we feel as if we are at rest. But relative to the pole star we are moving along a circular path. Also relative to the sun we are moving along an elliptical path around the sun. So actually speaking we are not at rest. In the same nothing is stationary. Everything is in motion. Rest means only a relative term.
