which statement is true about weight
1) pull of earth on a body
2) mass of a body
3) scalar quantity
4) unit per kilogram
1) is true on Earth, but a mass can have weight anywhere there are other bodies exerting a gravitational force, such as on the Moon.
3) is not a suitable chice because, technically, weight is a vector force
I don't like any of the choices.
