1)
a) Define mass and give the units that mass is measured in.
b) Define weight and give the units that weight is measured in.
2)
a) Write the equation that links mass, weight and gravitational field strength.
b) Would you describe mass and weight as being directly proportional to each other, or inversely proportional to each other?
c) What is the centre of mass?
3) An object has a mass of 15 kg.
