I. Mass and VWeight (Nr 2, Page 282)
Scientists measure an object’s mass in kilograms and its weight in Newton. If you know the
amount of mass of an object, you can calculate its weight, in Newtons, with the following formula:
Weight = Mass x 9.8
Create an application that lets the user enter an object’s mass and then calculates its weight. If
the object weighs more than 1000 Newtons, display a message in a Label control indicating that
it is too heavy and change the background colour of the label to red. If the object weighs less
than 10 Newtons, display a message in a Label control indicating that it is too light and change the
background colour of the label to blue. Otherwise display the weight, and change the background
colour of the label to green.
