The momentum observation principle can be mathematically represented as. Momentum is an objects mass multiplied by its velocity. According to the law of conservation of momentum total momentum must be conserved.
One of the most important laws of physics the law of conservation of momentum can also be expressed as mv constant where m is mass of the objects and v is their respective velocity.
So when the force acting on the system is zero then the total linear momentum of the system is either conserved or remains constant. The final momentum of the first object is equal to 8 kg 4 ms 32 Ns. Momentum is an objects mass multiplied by its velocity. One of the most important laws of physics the law of conservation of momentum can also be expressed as mv constant where m is mass of the objects and v is their respective velocity.
