Question

what is first low of motion and conservation of momentum define

Answer 1

Hey Mate...!!!

Pls find the answer below:

# First law of motion: It states that
“A body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it”.

# Conversation of momentum: Momentum is the tendency of the object to be in motion and therefore is a vector quantity. It is determined by the product of the mass of the object and its velocity. If both the objects are not experiencing any external forces, then the total momentum of the objects before and after the interaction is the same. This relation under the fundamental law of physics is known as the conservation of momentum.


Hope it helps..!!! :"))
