Answer 1

Newton's speed also known as the IDK

Answer 2

Newton's second law of motion also known as the real law of motion.

• The mathematical relationship which is given in the question is the mathematical explanation of the Newton's second law of motion.
• And, the Newton's second law of motion is popularly known as the real law of motion.
• Newton's second law of motion is known as the real law of motion because, we can derive both the first and third law of motion from this second law of motion by Newton.
