Question

Law of conservation written as m subscript 1 end subscript u subscript 1 end subscript plus m subscript 2 end subscript u subscript 2 end subscript equals m subscript 1 end subscript v subscript 1 end subscript plus m subscript 2 end subscript v subscript 2 end subscript Is about conservation of

  1. Speed    
  2. Mass    
  3. Velocity    
  4. Momentum    

Hint:

The formula for the law of conservation of momentum is: m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2.

The correct answer is: Momentum



    •  Law of conservation of momentum states that for two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied.
