IGCSE Physics: Motion, Forces and Energy

Cambridge IGCSE Physics 0625, Core and Extended: measurement, motion, forces, momentum and energy

8 lessons

A complete first unit of IGCSE Physics with worked examples on every page. You will use SI units and standard form, read and draw motion graphs, apply W = mg, density, F = ma and momentum, and calculate energy, work, power and efficiency. Every lesson ends with checks marked like an examiner would: the value and the unit both count, and answers in other units (2.5 kJ or 2500 J) are converted for you.

What you will be able to do

  • Use SI units, prefixes and standard form correctly in calculations
  • Calculate speed, velocity and acceleration and interpret distance–time and speed–time graphs
  • Apply weight, density, resultant force, F = ma and momentum to real situations
  • Calculate energy transfers, work done, power and efficiency, always with units
