Hello!

My teacher quickly explained it in class, but I can’t remember the difference between mass and weight. Could you please explain them to me?

Thanks in advance :)))

Hi Magic Octopus!

The mass of an object is the amount of matter it contains (measured in kilograms (kg)).

Weight, conversely, is the force with which Earth pulls an object towards it (measured in Newtons (N)). Weight is calculated using the following formula:

P = m × g

where P is the weight in Newtons (N), m is the mass in kilograms (kg), and g is the gravitational acceleration constant in Newtons per kilogram (N / kg).

The mass of an object is invariable, while weight varies according to the intensity of the gravitational force. The weight of an astronaut on Earth is not the same as on the Moon, since gravity isn’t the same!

I hope that answers your question! Feel free to ask us any other questions you may have!
