Weight, mass and gravitational field strength

• What is centre of mass?

  The point where the entire mass of an object can be considered to be concentrated.
• Mass is how much matter something has
• How do you calculate weight?

  Weight = Mass(kg) x Gravitational field strength(N/kg)
• The weight of an object is directly proportional to the mass of an object.
• what is mass measured in?

  Kg
• what is gravitational strength measured in?


  N/kg
• what is weight measured in?

  Newtons
