दोन वस्तूंचे वस्तुमान अनुक्रमे 200 gm आणि 300 gm असून ते एकाच रेघेवर व एकाच दिशेने 8 m/s आणि 4 m/s वेगाने जात आहेत. त्यांची टक्कर होते व टक्कर झाल्यावर पहिली वस्तू 5 m/s वेगाने गतिमान होते. टक्कर झाल्यावर दुसऱ्या वस्तूचा वेग काढा : Two objects having masses 200 gm and 300 gm, are moving along the same line in the same direction with velocities 8 m/s and 4 m/s, respectively. After the collision of the two objects, the first object moves with a velocity of 5 m/s. After collision, the velocity of the other object is :
Using the Law of Conservation of Momentum: m1u1 + m2u2 = m1v1 + m2v2. Substituting the values gives the final velocity of the second object as 6 m/s.
दोन वस्तूंची परस्पर क्रिया होत असताना त्यांच्यावर जर काही बाह्य बल कार्यरत नसेल, तर त्याचा एकूण संवेग, The two objects are interacting without external force, their total momentum
According to the Law of Conservation of Momentum, if no external force acts on a system of interacting objects, their total momentum remains constant (conserved).
खालीलपैकी कोणती भौतिक राशी टकरीच्या दरम्यान अक्षय राहते ? Which physical quantity conserved during collision ?
According to the Law of Conservation of Momentum, the total momentum of a system of colliding objects remains constant before and after the collision (in the absence of external forces).
