Sample AEPA Physics (NT308) Practice Questions

Try these sample questions to test your AEPA Physics (NT308) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A physics class investigates how ramp angle affects the acceleration of a cart. Which variable should students deliberately change?
A.The mass of the cart
B.The angle of the ramp
C.The type of motion sensor used
D.The acceleration calculated from the data
Explanation: The independent variable is the factor intentionally changed to test its effect. Since the investigation asks how ramp angle affects acceleration, the ramp angle is the independent variable. Cart mass and sensor type should be controlled, and acceleration is the dependent variable.
2On a velocity-time graph for one-dimensional motion, what physical quantity is represented by the slope of the graph?
A.Displacement
B.Speed
C.Acceleration
D.Momentum
Explanation: The slope of a velocity-time graph is change in velocity divided by change in time. That ratio is acceleration. The area under the graph, not the slope, gives displacement for one-dimensional motion.
3A student calculates 12.4 cm x 3.0 cm for the area of a rectangle. Which reported result uses the correct number of significant figures?
A.37.2 cm^2
B.37 cm^2
C.40 cm^2
D.37.20 cm^2
Explanation: For multiplication, the result should have the same number of significant figures as the measured value with the fewest significant figures. The values 12.4 and 3.0 have three and two significant figures, respectively, so the product 37.2 cm^2 should be reported as 37 cm^2.
4Which practice is most appropriate when students use a low-power laser in an optics activity?
A.Look directly into the beam only when it appears dim
B.Terminate the beam at a matte surface and keep it below eye level
C.Use shiny metal rulers so the beam path is easier to see
D.Aim the beam across the room to maximize distance
Explanation: Laser safety requires controlling the beam path and avoiding direct or reflected exposure to eyes. A matte beam stop below eye level reduces the chance of hazardous reflections. Even low-power classroom lasers must be treated as potential eye hazards.
5A model treats a rolling cart as a point particle on a frictionless track. Which limitation of the model should be recognized?
A.It cannot represent any motion in one dimension
B.It ignores energy losses and rotational effects that may be present
C.It requires all forces to be balanced
D.It makes acceleration impossible to calculate
Explanation: A frictionless point-particle model is useful but simplified. It neglects effects such as rolling rotation, bearing friction, air resistance, and energy dissipation. Recognizing the model's assumptions helps decide whether predictions match the real apparatus.
6Which estimate is the best order of magnitude for the length of a typical classroom lab table?
A.10^-3 m
B.10^-1 m
C.10^0 m
D.10^3 m
Explanation: A lab table is usually a few meters long, so its length is closest to 10^0 m. Order-of-magnitude estimates use powers of ten to check whether a result is physically reasonable. The other choices correspond to millimeters, centimeters, or kilometers.
7A cart starts from rest and moves with constant acceleration. To determine the acceleration from position-time data, which graph should produce a straight line whose slope equals one-half the acceleration?
A.Position versus time
B.Position versus time squared
C.Velocity versus position
D.Acceleration versus time squared
Explanation: For motion from rest with constant acceleration, x = (1/2)at^2 if the starting position is taken as zero. A graph of position versus t^2 is linear with slope a/2. This linearization is a common way to extract acceleration from motion data.
8A motion sensor repeatedly reports nearly the same cart speed, but later comparison with a calibrated photogate shows every reading is 0.20 m/s too high. Which description best fits the sensor readings?
A.Precise but not accurate
B.Accurate but not precise
C.Both random and accurate
D.Neither systematic nor reproducible
Explanation: Precision refers to how close repeated measurements are to each other, while accuracy refers to closeness to the accepted value. Repeated readings that agree with each other but are consistently too high are precise but biased. The bias indicates poor accuracy.
9Which conclusion is best supported if two variables show a strong correlation in a physics investigation?
A.One variable definitely causes the other
B.The variables are related, but additional evidence is needed to establish causation
C.The data must be invalid because physics variables cannot correlate
D.The relationship must be linear
Explanation: Correlation means the variables vary together in the data set. Causation requires a controlled design, a plausible mechanism, and evidence that confounding variables have been addressed. A strong correlation can guide further investigation but does not by itself prove cause and effect.
10Which expression is dimensionally consistent for the displacement x of an object moving with initial velocity v0 and constant acceleration a for time t?
A.x = v0/t + at
B.x = v0t + (1/2)at^2
C.x = v0 + at^2
D.x = a/t^2
Explanation: Each term in an equation for displacement must have units of length. The term v0t has units of length, and (1/2)at^2 also has units of length. Therefore x = v0t + (1/2)at^2 is dimensionally consistent.

AEPA Physics (NT308) Study Tips from Top Performers

1Study by official weighting: spend the most time on mechanics, then keep electricity and magnetism and modern physics as major second-tier priorities.
2Practice translating between words, diagrams, graphs, vectors, and equations because the profile repeatedly emphasizes multiple representations.
3Use units as a check on every quantitative answer; dimensional analysis quickly exposes many plausible distractors.
4For electricity and magnetism, master field direction, potential, circuit reductions, Kirchhoff reasoning, magnetic force directions, and Lenz's law.
5For waves and optics, connect the same wave principles across sound, strings, pipes, light, lenses, interference, diffraction, and polarization.
6For modern physics, do not skip thermodynamics; AEPA places thermal energy and kinetic theory inside the Modern Physics domain.
