• Weight


  The force of gravity on an object, measured in newtons (N)
• Mass


  The quantity of matter in an object, measured in kilograms (kg)
• On Earth, the force of gravity is 10 N on every 1 kg of mass
• Weight equation


  Weight (N) = mass (kg) x 10 (N/kg)
• Using a formula triangle


  Cover the part you want to find, then do the calculation shown in the uncovered part
• Gravity between two masses


  Similar to magnetic force between two magnets
• Magnets can repel, but gravity cannot repel
• Force meter
