Question

((:In a collision of two bodies in absence of
other force field
collision must be central
collision must be direct
total kinetic energy of bodies must be
preserved
total momentum must be preserved
​

Answer 1

Answer:

Explanation:

Collison must be Central

Answer 2

Answer:

D

Explanation:

According to the statement given, the correct option based on options given is option D.

In a collision of two bodies in absence of other force, total momentum must be preserved

In general, when an object collides with other object, then the law of conservation of momentum is maintained between them. Also overall energy will also remain same but it could be converted from one form to another
