GCSE Physics AQA FT Topic 1: Energy - Efficiency Questions Worksheet

Foundation Tier efficiency calculations worksheets to help GCSE Physics students build confidence with the efficiency equation:

efficiency = useful output energy transfer ÷ total input energy transfer

The questions increase gradually in difficulty, beginning with substituting values to calculate efficiency as a decimal, then calculating efficiency as a decimal and a percentage for everyday devices such as a kettle, a filament bulb and a toy car motor. The final section introduces rearranging the equation, with the rearranged equation given, to calculate the useful output energy or the total input energy.

These efficiency calculations worksheets include:

• Practice questions
• Clear worked examples
• A separate scaffolding sheet
• Quick answers and fully worked solutions
• PDF and editable Word versions

Ideal for classroom practice, independent study, homework, intervention or revision. The separate scaffolding sheet gives students a fill-in-the-blanks frame for every section, so they can complete the same Foundation Tier questions with additional support.

Suitable for Foundation Tier students studying AQA GCSE Physics (4.1.2.2) or Combined Science: Trilogy (6.1.2.2), as well as other GCSE exam boards.
