Question

1. What do you understand by the term motion?​

Answer 1

Answer:

Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

Explanation:

Hope it helps you

$\boxed{\sf \green{★ \: Rectilinear\:motion\:}}$

When we require only one co-ordinate axis along with time to describe the motion of a particle it is said to be in linear motion or rectilinear motion.

_______________________________

$\boxed{\sf \pink{★ \: Circular\:motion\:}}$

In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. ... Since the object's velocity vector is constantly changing direction, the moving object is undergoing acceleration by a centripetal force in the direction of the center of rotation

_______________________________

$\boxed{\sf \blue{★ \: Periodic\:motion\:}}$

Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave

_______________________________

$\boxed{\sf \red{★ \: Rotational\:motion\:}}$

Rotation around a fixed axis or about a fixed axis of revolution or motion with respect to a fixed axis of rotation is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession.
