Naturwissenschaften — Physik for the Abitur Exam

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

• !Forgetting to use SI units consistently in calculations
• !Lenz's law direction errors in electromagnetic induction problems
• !Confusing wave-particle duality concepts for light and electrons

Study tips

• 1Build a formula card for each Abitur Physik topic — mechanics, electrodynamics, optics, atomic physics.
• 2Practice drawing and labelling physics diagrams: force vector diagrams, circuit diagrams, wave diagrams.
• 3For electromagnetic induction, always apply the three-finger rule (Drei-Finger-Regel) or Lenz's law before calculating.

1. 1

   Ein Elektron wird durch eine Spannung von 100 V beschleunigt. Welche kinetische Energie erhält es? (An electron is accelerated through 100 V. What kinetic energy does it gain?)

   • A100 J
   • B1.6 × 10⁻¹⁷ JCorrect
   • C9.1 × 10⁻³¹ J
   • D1.6 × 10⁻¹⁹ J
   Why this answer?

   E_kin = e × U = 1.6 × 10⁻¹⁹ C × 100 V = 1.6 × 10⁻¹⁷ J. The electron charge e = 1.6 × 10⁻¹⁹ C, and the kinetic energy gained equals the work done by the electric field: W = q × U.
