Question

what is a point object

Answer 1

Point object :- Point object is an expression used in kinematics: it is an object whose dimensions are ignored or neglected while considering its motion.

Answer 2

Hey friends here is your answer ____________________________________


Point object is an expression used in kinematics: it is an object whose dimensions are ignored or neglected while considering its motion.

A point object refers to a tiny object which is calculated or counted as dot object to simplyfy the calculations. A real object can rotate as it moves. For example, a ball will be spinning while it is moving in a trajectory. Also, a body - for example, a falling water drop - may vibrate as it moves, These complications can be avoided by considering the motion of a very small body called a point object.

Mathematically, a particle is treated as just a point, an object without extension, so that rotational and vibrational motions are not involved.

Actually, there is no such thing in nature as an object without extension. The concept of a particle or a point object is very useful because real objects often behave to a great extent, like particles. A body need not be 'small' in the usual sense of the word, in order to be treated as a particle.

For example, if we consider the distance from the Earth to the sun, with respect to the distance between them, both the Earth and the sun can be treated as point objects. We can find out a great deal about the motion of the sun, planets and other celestial bodies, without appreciable error, by treating these bodies as particles.

Thus, any object can be treated as a point object if it covers distances which are much greater in comparison to its size....
