CAIE IGCSE Physics Mass and Weight Question Bank

Practise distinguishing mass from weight, using W = mg, comparing masses with a balance and explaining how gravitational field strength changes weight but not mass.

Syllabus
2026–2028
Course
Physics 0625

Exam points

  • distinguish invariant mass in kilograms from gravitational weight in newtons
  • rearrange W = mg for weight, mass or gravitational field strength with correct units
  • compare locations by keeping mass constant and changing weight with the local field strength
