Using ln and log for A Level Physics Worksheet
A-level ln and log worksheet with answers: learn logarithms, solve exponential equations and interpret graphs through capacitor and radioactive-decay applications.
What is covered
Questions and skills covered
The worksheet contains 7 pages of printable questions. A separate 7-page solutions PDF makes it easy to mark, review or share answers after the activity.
- Meaning of base-ten and natural logarithms
- Inverse exponential functions and calculator use
- Product, quotient and power laws
- Rearranging for an unknown exponent
- Capacitor discharge and an optional charging extension
- Background-corrected radioactive count rates, decay constant and half-life
- Plotting ln-normalised data, interpreting gradients and comparing ln with log10
About this activity
A hospital instrumentation team analyses a capacitor timing circuit and background-corrected radioactive reference measurements. Guided fluency leads to exponential equations and logarithmic graphs.
Before you start
A-level learners who can rearrange equations and use a scientific calculator. Physics models are supplied; this is guided maths practice with second-year applications.
