The SI unit Newton is named after which scientist?

The SI unit Newton is named after which scientist?

• A. Isaac Newton
• B. Albert Einstein
• C. James Watt
• D. Nikola Tesla

Answer: (A)

The SI unit of force is named to honor Isaac Newton for his foundational work in mechanics. A newton is defined as the force that gives a 1-kilogram mass an acceleration of 1 meter per second squared, so 1 N = 1 kg·m/s^2. This naming reflects Newton’s pivotal role in describing motion and forces. The other scientists are celebrated for different contributions: Einstein for relativity, Watt for power, and Tesla has a magnetic-flux-density unit named after him, but not the unit of force.
