A newton is a unit of measurement used to measure force. Therefore, a newton has no actual weight. Although a newton is a unit of force, weight is used as a reference point in determining an object's force.
One newton is the amount of force required to accelerate an object that weighs one kilogram one meter per second each second. The force of Earth's gravity on a person who weighs 70 kilograms is approximately 686 N. The newton is named after the famous physicist Isaac Newton in recognition of his work in establishing his second law of motion, which involves the measurement of net force on an object.
