The aim of this activity is to understand weight, and be able to use the formula W = mg. Models of balls falling on the earth, the moon and in space, are used to show the dependence upon gravitational field. The operation of a spring balance (or newton balance) is also seen.
This item teaches:
- the definition of g as force per unit mass
- about the weight equation: weight = mass x gravitational field strength
- how weight would vary in different parts of the solar system
- the definition of weight
