Comparing Mass and Weight

The video explains that the mass of an object remains constant regardless of its location, such as on Earth or the moon. However, the weight of an object varies depending on the gravitational pull at its location. The metric unit of weight is the Newton, which is a measure of force. On Earth, a 1-kilogram mass weighs 9.8 Newtons. While scientists use Newtons to describe weight, everyday usage often involves metric units of mass or English units like pounds.

Explain the relationship between mass and weight.
