Question

When we can use the concept of point object   ​

Answer 1

Answer:

Standard Algebraic Identities List

Identity I: (a + b)2 = a2 + 2ab + b2

Identity III: a2 – b2= (a + b)(a – b)

Identity IV: (x + a)(x + b) = x2 + (a + b) x + ab.

Identity V: (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.

Identity VI: (a + b)3 = a3 + b3 + 3ab (a + b)

Answer 2

Answer:

hi army

good morning ❤

Explanation:

Point object is an expression used in kinematics: it is an object whose dimensions are ignored or neglected while considering its motion. ... The concept of a particle or a point object is very useful because real objects often behave to a great extent, like particles.
