What are examples of intermittent motion?
Examples of intermittent motion include windshield wipers on a car, pendulum clocks, and sewing machines. These devices operate cyclically with periods of rest in between movements.
What does it mean that motion is relative?
Motion being relative means that an object's motion can only be described in relation to another object's motion or a reference point. This concept is described by Newton's laws of motion and is a fundamental principle in physics. It implies that there is no absolute state of rest or motion.
Are rest and motion absolute or relative terms?
Rest and motion are relative terms, meaning they are defined in relation to a particular frame of reference. An object at rest in one frame of reference may be in motion in another frame. This concept is a key aspect of Einstein's theory of relativity.
What is the definition of rest in physics and how does it relate to the concept of motion?
Rest in physics refers to an object being stationary or not moving. In the context of motion, rest serves as a reference point to determine an object's change in position or velocity. When an object is at rest, it provides a frame of reference for observing and measuring motion, allowing us to analyze and understand the movement of objects in relation to their stationary state.
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.

How do you tell when an object is in motion?
The fact is that it always is ... in relation to something. For an object to be at "rest" there must be a second object to compare it with.
What is absolute rest and absolute motion?
motion : when a body is moving or changing its position with respect to its surroundings is called motion. rest: when a body is not moving or fixed at a place with respect to its surroundings is called rest.

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.

Can a body at rest b regarded in the state of motion?
Motion is measured as relative to a set point.A rock sitting on the ground is at rest in relation to the groundThe rock and the ground are spinning with the surface of the planet.The planet is moving in the solar systemAnd so on
How can you say that rest and motion are relative terms?
Rest and motion are relative terms because an object's state of rest or motion is defined in relation to another object. An object can be at rest relative to one object but in motion relative to a different object. This concept is based on the principle of relativity in physics, as described by Galileo and later by Einstein in his theory of special relativity.
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.
Is there anybody in this world is in absolute rest?
No, according to the principle of relativity in physics, there is no frame of reference that is considered to be in absolute rest. All motion is relative, meaning that an object's state of rest or motion can only be described in relation to another object or a particular frame of reference.
