2 Making SENSE of Formulas and Laws The potential energy E pot of a body is given by the product of its mass m, its height h and the gravitational constant g. E pot =m·h·g Apply the formula: - find example (window washer, washing machine) - play with the formula (washing machine to 2 nd or to 4 th floor) - be critical about the formula: is it really much more difficult to lift a filled box than it is to lift an empty one?
