Weight can be measured using extension or compression spring balances
In real life, mass is commonly referred to as weight, but they are different. Mass is measured in grams and kilograms, while weight is measured in Newton
The weight of an object on the Moon is less than its weight on Earth because the Moon has a weaker gravitationalfieldstrength than Earth
The mass of an object is the amount of matter in it and does not change with location
The force experienced is strongest on the surface of the Earth and gets weaker further away
Earth is surrounded by a gravitational field. Field lines are drawn to represent the gravitational field
The weight of an object on the moon is one-sixth of its weight on Earth, but the mass of the object is the same everywhere
The Earth's gravity is experienced by any object near it
The SI unit of mass is the kilogram (kg) and the unit of weight is the newton (N)
Weight is a measure of the force of gravity exerted on an object. The more mass an object has, the greater the force acting on it
On Earth, the gravitational field strength g is approximately 10 N/kg at the surface of the Earth. The gravitational field strength on the Moon is approximately 1.6 N/kg
Gravitational field
The region (space) surrounding the Earth where gravity is experienced
The gravitational force acting on a mass changes with location depending on the gravitational field strength in that location
