What are Moving Objects?

An object is said to be moving only when it changes its position.

Therefore, a moving object is characterized by its position, its direction of motion, and its direction of movement.

Let’s consider a block of mass, ‘m’ kept on the table.

Now, if we give it a push, it starts moving in the direction of force.

Newton's first law states that if an external force is applied to this block, it changes its position or sets into motion.

Motion Can Be Found In Many Real-life Objects, Such As:

A ball thrown upward

A flying aeroplane

The falling of the dust particles on beating the floor mat.

Running animals

An electron moving in a direction perpendicular to the magnetic field.

Examples Of Moving Objects

Motion can be of various types, some of them are discussed with examples below:

Rectilinear Motion - Motion of a body along the straight line.

Periodic Motion: The motion repeated after a fixed interval of time.

(Image to be added soon)

The revolution of planets around the sun in a fixed interval of time.

Such a motion is also called the simple harmonic motion.

Circular Motion:

A body follows a circular locus such that the force required to move a body uniformly in a circle acts along the radius and towards the center of the circle.

With continuous change in the direction of motion of the body, there is a change in velocity of the body and hence, it undergoes an apparent acceleration called the centripetal acceleration.

For example, when a stone is tied to a string and on applying the force, the stone starts rotating about a fixed point.

$\color{aqua}\huge\bold\star\underline\mathcal{NON\:MOVING\: OBJECTS}\star$

MOBILITY -> When the position of an object changes with respect to the time, then that object is known to be in motion.

The mobility of an object depends on the other object whose reference we want to take.

For example :-

Two persons sitting in a train are at rest in the reference of each other, so both of them will be called as non-moving. But for the person standing out of the train , both of them are in motion.

So it all depends on the reference.

Answer 2

i) Which one can move on the earth like motion that is called moving objects XD

ii) Which one can't move one inch like mountain or others

I hope its won't helpful forever ;)
