Describiendo a la materia y sus propiedades: comparando masa y peso

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 force at its location. The unit of weight is the Newton, which is a measure of force. On Earth, a 1 kg mass weighs 9.8 Newtons. While scientists use Newtons to describe weight, everyday measurements often use units of mass like grams or pounds.

What remains unchanged when an object is moved from Earth to the Moon?

• Its density

• Its volume

• Its mass

• Its weight
