Question

Newton's second law of motion leads to the law of conservation of
1. Angular momentum
2. Energy
3. Mass
4. Momentum

Answer 1

Correct Answer - Option 4 : Momentum

The correct answer is Momentum.

• Momentum is a vector quantity, it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. 
• In the absence of a net external force acting on a collection of particles, their total momentum never changes, it is the meaning of the law of conservation of momentum.

• Angular momentum-
  • Angular momentum is a vector quantity, requiring the specification of both a magnitude and a direction for its complete description
  • Angular momentum, property characterizing the rotary inertia of an object or system of objects in motion about an axis that may or may not pass through the object or system.
  • The Earth has orbital angular momentum by reason of its annual revolution about the Sun and spins angular momentum because of its daily rotation about its axis.
• Energy- 
  • It is the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. 
  • All forms of energy are associated with motion. For example, any given body has kinetic energy if it is in motion.​
