Most people use the word weight when they really should be talking about mass.
The ideas are often confused.
Jack has Mass and weight
Mass tells us how much material we have in our body
On Earth, every Kg is pulled down by gravity with a force of 10 N
What happens to Jack's weight on the moon?The mass of an object NEVER CHANGES no matter where you take it.
An objects weight will change if the place has a different force of gravityIF Jack went to the moon his weight changes. The moon has a pull only one sixth that of Earth He still contains the same amount of material. If Jack could travel to the moon his mass (40Kg) would be the same as on Earth.
Weight is measured in Newtons (N)
Mass is measured in grams (g) and Kilograms (Kg)
Weight tells us how strongly the force of gravity is pulling on Jack's mass
