Question

State of motion is described by
(a) Position of rest
(b) Position of motion
(c) Both by the state of rest or motion
(d) None of these

Answer 1

The state of motion is described by both the state of rest and motion.

Detailed answer

The state of motion is usually defined as the speed and the direction of a motion

• An object can be both in the form of rest or motion to be considered as the object to be in the state of motion
• There are two types of motion that are uniform and non-uniform motion.
• When the speed of the object is zero it is said to be at rest but still in the state of motion.
• An example of a state of motion is when a body comes to rest from accelerating for a time and reduces the speed is considered an example as the speed of the body decreases so its state of motion changes

Answer 2

State of motion is described by (c) Both by the state of rest or motion.

What is state of motion?

• State of motion of any object can be explained by defining three quantities or terms i.e. distance, speed and time.
• Distance of the object is total path covered by the body.
• Time is the duration or interval taken by body to cover the total distance.
• Speed of the object is the rate of change in position with respect to time.
• When an object is at rest, the speed of the object is zero which means there is no change in position of the body.
• When an object is in motion, there is non-zero speed of the body and there is change in position which means that the body covers some distance in a given interval of time.
