Most Common AP Physics 2 Mistakes (And How to Fix Them)
AP students consistently make the same mistakes on the AP Physics 2 exam. Here are the most frequent errors and proven methods to avoid them and maximize your score.
Mistake
Common Mistake
The Problem
Frequency
How to Fix It
1
Confusing Pressure and Force
Using force and pressure interchangeably in fluid problems
Very High (65% of students)
Always ascertain whether the question calls for pressure or force; use the proper units and remember that P = F/A.
2
Misapplying the Ideal Gas Law
Using PV = nRT incorrectly or neglecting to convert temperature to Kelvin
Extremely High (70% of students)
To convert Celsius to Kelvin, always add 273 and make sure the pressure and volume units are consistent.
3
Sign Errors in Thermodynamics
The first law of thermodynamics contains inaccurate work and heat signs.
High (55% of students)
From the outset, establish a clear sign convention: the system’s work is positive and heat entering the system is positive.
4
Confusing Electric Potential and Electric Potential Energy
Assuming that voltage and potential energy are equal quantities
Very High (60% of students)
Remember that the energy of electric potential is equal to the product of charge and electric potential (U = qV).
5
Incorrect Application of Kirchhoff’s Rules
Make mistakes when applying the loop or junction rules.
High (50% of students)
Choose the current direction for each branch; voltage drops are negative when assuming a current.
6
Right-Hand Rule Errors in Magnetism
Using the incorrect fingers or applying rules in the incorrect context
Very High (65% of students)
The three right-hand rules – field from current, force on moving charge, and force on current – should all be practiced separately.current, field derived from current
7
Ray Diagram Mistakes in Optics
Inaccurately drawing rays or positioning images
High (55% of students)
For lenses or mirrors, draw all three principal rays; the image forms where the rays converge or seem to
8
Misunderstanding Lenz’s Law
Predicting the incorrect direction of an EMF or induced current
High (50% of students)
Induced effects are always opposed to the change that causes them; once the opposition direction has been established, apply the right-hand rule.
9
Forgetting about Conservation Laws
Not knowing when to use charge or energy conservation
Medium-High (45% of students)
Examine each issue for conserved quantities, such as flux in inductors, charge in circuits, and energy in isolated systems.
10
Not Showing Work on FRQs
Giving definitive answers without any explanations or steps in between
Extremely High (70% of students)
Explain physical reasoning in full sentences and write out each equation, substitution, and calculation step.
11
Photoelectric Effect Misconceptions
The maximum kinetic energy of photoelectrons is influenced by the intensity of thought.
Medium-High (45% of students)
Recall that intensity influences the quantity of photoelectrons rather than their maximum energy (KE_max = hf – φ).
12
Unit Conversion Errors
Mixing unit systems or improperly converting units
Extremely High (65% of students)
Make sure the final answer units make sense for the question by first converting all quantities to SI units.
13
Misinterpreting Graphs
Incorrectly interpreting graphs or failing to extract important information
High (50% of students)
Determine the meaning of each axis; search for areas, intercepts, and slopes; comprehend the physical meaning of graph shape
14
Poor Time Management
Taking too long on challenging questions while ignoring others
Medium-High (40% of students)
Give each FRQ 15 minutes; if you’re stuck after 3–4 minutes, move on and come back later if you have time.
15
Not Using Provided Equation Sheet
Attempting to commit all formulas to memory or utilizing the wrong equations
Medium (35% of students)
During all practice exams, use the official College Board equation sheet and become familiar with the locations of formulas.
