A point object is refers to a tiny object which is calculated or counted as dot object to simplyfy the calculations...
An object can be treated as a point particle if internal motions are not important and if the object is small in comparison to the distance it moves. http://teachers.redclay.k12.de.us/william.baker/Physics%20Files/physics%20solutions%20manual%20for%20practice-end%20chap.pdf
According to the Physics Classroom, "When the object is located at the focal point, no image is formed."http://www.physicsclassroom.com/class/refrn/Lesson-5/Converging-Lenses-Object-Image-Relations
No, it is also used by students taking Physics and their professors.You can use kinematics to find a shortcut (resultant vector) on how a plane or ship moves. You can use robot kinematics to find how a robotic arm will move. You can use it to study how particles move. You can use linear kinematics to discuss how a football player moves across the field. You can use it to design a track for a Hot Wheels racecar to go on.***Kinematics equations are used in LOTS of professions. For example, a person investigating a car accident to determine fault could use kinematics, dynamics and momentum equations to evaluate the claims of each driver (as to initial speed or coming to a full stop at a stop sign) from skid marks, final distance & direction from the point of impact.No, it is also used by students taking Physics and their professors.

tell me what is meant by point
Lever In physics, a lever (from French lever, "to raise", c.f. a levant) is a rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object.
It's mean roads that take you on a place or church chicken
It keeps you on the ground.
Quantum physics is the first turning point in physics and the second revolution is due to relativity theory
From Jacob's point of view, Chapter 18 From Bella's point of view, Chapter 19
A shadow is an absence of light from a point-source because it has been blocked by an object. The object's shape is projected on to the ground, wall or other surface. There might be light from another source illuminating the part that is shadowed, and that might be coloured.
