What do you mean by state of motion of an object?
The state of motion of an object describes how it is moving in relation to its surroundings. It includes whether the object is at rest or moving, as well as the speed and direction of its movement. This concept is fundamental in physics for understanding the behavior of objects in motion.
Is it correct to say that no force acts on a body at rest?
No, it can be moving. A body is said to be in equilibrium when the forces acting on it cancel each other out, that is, the body is not accelerating. Therefore an object might be moving at a constant speed and be considered in equilibrium.
1 Can the state of absolute rest or motion be defined for any object?
Absolute rest is commonly called absolute zero. To cool something by extracting energy it must be placed in an environment with less average energy than it contains; this requires the environment to be already at or below absolute zero, which requires something to make it that temperature. This thing must be at or below absolute zero as well... and we enter a causality loop where being able to do one thing requires it to have been done. Thus it is impossible.
How are rest and motion relative terms?
When an object is at rest, it is only at rest compaired to the observer. Consider that if you are in a moving vehicle then your passenger is at rest from your point of view, but to an observer, outside the vehicle the passenger and you are both in motion. Similarly to you inside the vehicle the observer outside is moving . as the earth itself is in motion, as well as the sun and in fact the whole galaxy, their is no way to absolutely define an at rest state, so all motion is measured relative to the observer, who is assumed to be at rest compaired to the observation.
How does inertia affect motion?
Inertia can be defined as the relunctance of a body to acceleration. Therefore, the greater the inertia of a body, the less it will accelerate under a given force. Inertia is directly related to mass. The greater the mass, the greater the inertia.

Can a body be at rest as well as in motion at the same time . explain?
No, a body cannot be at rest and in motion at the same time in the same frame of reference. This is known as the principle of relativity in physics, which states that an object cannot have multiple velocities at the same time in a single reference frame.
Do you die when you sleep, or is it just a natural state of rest for the body"?
During sleep, your body rests and rejuvenates, but you do not die. Sleep is a natural state of rest that is essential for overall health and well-being.
Is it correct to say that no force acts on a body at rest?
No, it can be moving. A body is said to be in equilibrium when the forces acting on it cancel each other out, that is, the body is not accelerating. Therefore an object might be moving at a constant speed and be considered in equilibrium.
What are the ways to put your body at rest?
Do not make your body very weak...so that, you will sleep or rest well...
Why it is difficult to catch a solid ball as compare to a hollow ball of equal radius?
it can be understood well with the knowledge of moment of inertia... newton's law states " a body continues to be in a state of rest, or a state of motion in a straight line, until an external force is applied to overcome it." now the greater is the mass of an object the more is its moment of inertia, so more force has to be applied to bring a ball to rest when it is moving..

Can a body be regarded in a state of rest as well as in motion at the same time?
We suppose it can, according to two reports from different observers. An observer on the ground sees a passenger jet whizzing by at 400 mph, while a passenger aboard the aircraft at the same time observes it to be sufficiently motionless that she can nap or read a book.
Can a body have an acceleration when it is momentarily at rest?
No, a body cannot have acceleration when it is momentarily at rest. Acceleration is the rate of change of velocity over time, so if the body is at rest, its velocity is zero, and therefore its acceleration is zero as well.
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.
