Abstract You should already be familiar with the following concepts: MASS: A measure of the amount of material in a body. In SI units mass is measured in kilograms (kg) or in our context in Tonnes (1 Tonne $$=$$ 1000 kg). WEIGHT: The vertical force acting downwards on a given mass in a gravitational field. This force is dependent on the body mass and the local acceleration due to gravity: $$ w = m g $$ where $$w=$$ weight measured in newtons (N), kilonewtons (kN) or meganewtons (MN) and g $$=$$ 9.81 m/s $$^2$$ as a good average earth value of gravitational acceleration. Note: 1 N $$=$$ 1 kg 1 m/s $$^2$$ 1 kN $$=$$ 1000 N, 1 MN $$=$$ 1000 kN $$=10^6$$ N. The weight of a 1 Tonne mass is 9.81 kN.
