Sample ORELA Physics (NT308) Practice Questions

Try these sample questions to test your ORELA 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 tests how the distance from a bar magnet affects the magnetic field strength measured by a probe. Which variable should students deliberately change?
A.The type of magnetic-field probe
B.The distance between the magnet and the probe
C.The field strength recorded by the probe
D.The room in which the investigation is conducted
Explanation: The independent variable is the factor intentionally changed to test its effect. In this investigation, distance from the magnet is changed, while the measured magnetic field strength is the dependent variable.
2Which practice is most appropriate when students use a low-power laser for an optics lab?
A.Look into the beam only if it appears dim
B.Use shiny metal metersticks to make reflections visible
C.Keep the beam below eye level and terminate it on a matte surface
D.Aim the beam across the room so the path is longer
Explanation: Laser safety requires controlling both the direct beam and reflected beams. Keeping the beam below eye level and ending it on a dull beam stop reduces the chance of eye exposure.
3A student multiplies 12.0 cm by 0.43 cm to find an area. Which reported result uses the correct number of significant figures?
A.5 cm^2
B.5.2 cm^2
C.5.16 cm^2
D.5.160 cm^2
Explanation: For multiplication, the result should have the same number of significant figures as the factor with the fewest significant figures. The value 0.43 has two significant figures, so 12.0 x 0.43 = 5.16 should be reported as 5.2 cm^2.
4Why should students repeat several trials when measuring the period of a pendulum?
A.Repeated trials eliminate the need for units
B.Repeated trials reduce the effect of random measurement variation
C.Repeated trials prove the hypothesis must be true
D.Repeated trials make systematic calibration errors impossible
Explanation: Repeating trials and averaging helps reduce the influence of random timing errors. It does not remove all possible errors, but it makes the measured period more reliable.
5A model treats a thrown ball as a point particle moving through vacuum. Which limitation should be recognized?
A.The model cannot describe any projectile motion
B.The model ignores the ball's size, spin, and air resistance
C.The model requires the ball to have zero mass
D.The model prevents the use of Newton's laws
Explanation: A point-particle vacuum model is useful for basic projectile calculations, but it omits rotation, drag, lift, and the physical size of the ball. Recognizing those assumptions helps decide when the model is adequate.
6A cart starts from rest and moves with nearly constant acceleration. Which graph should be linear if position is measured from the starting point?
A.Position versus time
B.Position versus time squared
C.Velocity versus time squared
D.Acceleration versus distance
Explanation: For motion from rest with constant acceleration, x = (1/2)at^2. A graph of position versus t^2 should be a straight line with slope equal to a/2.
7A sensor gives nearly identical speed readings in repeated trials, but a calibrated photogate shows all readings are 0.15 m/s too high. How should the sensor readings be described?
A.Accurate but not precise
B.Precise but not accurate
C.Neither precise nor reproducible
D.Random but unbiased
Explanation: Precision describes agreement among repeated measurements, while accuracy describes closeness to the accepted value. Reproducible readings with the same offset are precise but affected by systematic error.
8In a data table, x increases by 2.0 units each trial while y increases by approximately 6.0 units each trial. Which relationship is best supported?
A.The variables are approximately linearly related
B.The variables are inversely related
C.The variable y is constant
D.The variable y is proportional to x squared
Explanation: A nearly constant change in y for each equal change in x indicates an approximately constant slope. That pattern supports a linear relationship over the measured range.
9A news article claims a wireless charger is 'nearly lossless' because it does not feel hot during use. Which critique is most scientifically appropriate?
A.The claim is proven because temperature is the only measure of efficiency
B.The claim should be checked by comparing input power with useful output power
C.Efficiency cannot be measured for electrical devices
D.A cool surface means energy conservation has been violated
Explanation: Efficiency is the useful output energy or power divided by the input energy or power. Surface temperature alone does not account for all energy transfers, so electrical measurements are needed.
10How did X-ray diffraction most directly contribute to chemistry and biology?
A.It measured the age of fossils by radioactive decay
B.It inferred molecular and crystal structures from diffraction patterns
C.It generated electrical power from nuclear reactions
D.It separated isotopes using magnetic fields
Explanation: X-ray wavelengths are comparable to atomic spacings, so diffraction patterns reveal structural information about crystals and molecules. This made the technique important in fields such as chemistry, materials science, and molecular biology.

ORELA Physics (NT308) Study Tips from Top Performers

1Use the official 14/28/22/14/22 profile to allocate study time; Mechanics deserves the largest single block.
2Practice translating between words, diagrams, equations, graphs, force diagrams, circuit diagrams, ray diagrams, and energy bar charts.
3Use units and limiting cases as checks on quantitative answers; dimensional analysis catches many plausible distractors.
4For mechanics, make free-body diagrams and define the system before applying Newton's laws, energy, momentum, torque, or angular momentum.
5For electricity and magnetism, drill field direction, potential, circuit reductions, Kirchhoff reasoning, magnetic-force right-hand rules, and Lenz's law.
6For waves and optics, connect the same wave principles across sound, strings, pipes, light, lenses, interference, diffraction, and polarization.
7For the Modern Physics domain, do not skip thermodynamics; ORELA places thermal energy and kinetic theory inside the same weighted domain as quantum, relativity, atomic, and nuclear physics.
