Can a body be regarded in the state of rest as well as in motion at the same time?

Answer 1

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 thing

as the 'real' one. Every state of motion is relative to something else.

Answer 2

This is just based on an example i thought of but if you are in a vehicle the vehicle has it's own microclimate so although you are technically moving at whatever speed the car is, you are actually still at rest because you are not exposed to the conditions of outside and you do not have to physically propel the vehicle as if you were on a bike for example. so you are in a state of motion in a car but your body is still at rest.

Answer 3

In Newton's view of our Universe, yes. He believed that there was an absolute frame against which an object could be at rest.

Albert Einstein refuted that idea, stating that an object could only have a velocity relative to another frame, and that no frame could be declared the "absolute" one.

Answer 4

A body at rest is stationary and motion is moving. I think what you mean is that an object of a constant velocity is considered at rest in your terms as it it not experiencing force.

Answer 5

Yes, simply put you may be "at rest" sitting stationary in a chair but you are actually in motion on the Earth as it orbits the Sun.

Answer 6

No. Motion is a change in position of an object with respect to time and its reference point.

Answer 7

Use less energy
