Question 1
Energy stored in a capacitor C = 8 pF charged to V = 9 V. What is the energy?
Correct Answer:
3.24e-10 J
Explanation:
Energy stored in a capacitor is given by U = 1/2 C V^2. Convert the capacitance to farads: 8 pF = 8 × 10^-12 F, and square the voltage: V^2 = 9^2 = 81. So U = 0.5 × (8 × 10^-12) × 81 = 0.5 × 648 × 10^-12 = 324 × 10^-12 = 3.24 × 10^-10 J. This matches 3.24e-10 J. A common mistake is dropping the 1/2 factor, which would give 6.48e-10 J.
Question 2
According to Newton's Second Law, acceleration is related to force and mass in which way?
Correct Answer:
Acceleration is directly proportional to the applied force and inversely proportional to the mass
Explanation:
Newton's Second Law says how fast an object speeds up depends on the net force acting on it and its mass. The acceleration is proportional to the net force and inversely proportional to the mass, written as a = F/m for constant mass. That means pushing harder increases acceleration, while carrying more mass reduces it. For example, doubling the force on the same mass doubles the acceleration, whereas doubling the mass with the same force halves the acceleration. The direction of acceleration matches the direction of the net force. If someone suggested it's inversely proportional to both force and mass, that would imply more force gives less acceleration, which isn’t correct. If acceleration were force times mass, the units would not match and the relationship would be different from what we observe. If acceleration were independent of force, applying a force would have no effect, which contradicts everyday experience.
Question 3
Heat energy is also known as what?
Correct Answer:
Thermal energy
Explanation:
Heat is energy in transit due to a temperature difference, while thermal energy is the energy contained in a system from the microscopic motion and interactions of its particles. In everyday usage, “heat energy” often means the energy stored in a substance as a result of its temperature, which is precisely what thermal energy describes. When you add heat to a system, its thermal energy increases (temperature can rise, or a phase change can occur while energy goes into changing the state). When you remove heat, the thermal energy decreases. The other options aren’t correct fits: energy transformation describes how energy changes forms, not a form of energy itself; efficiency is a ratio, not a kind of energy; electric energy is a specific form of energy tied to electric charges, not the general concept of heat energy. Therefore, thermal energy is the best answer.
Question 4
Using Ohm's Law, calculate the current when the voltage is 9 V and the resistance is 3 Ω.
Correct Answer:
3 A
Explanation:
Current is the rate at which electric charge flows, and Ohm's law links current to voltage and resistance with I = V / R. So the current equals the voltage divided by the resistance. With 9 V across 3 Ω, I = 9 / 3 = 3 A. A quick check: if 3 A flowed through 3 Ω, the voltage would be I R = 3 × 3 = 9 V, which matches the given voltage. The other numbers don’t fit because 1 A would yield only 3 V across 3 Ω, and 27 A would require about 1/3 Ω to produce 9 V. Therefore, the current is 3 A.
Question 5
A hockey puck sliding on an ice rink is often described as motion that occurs with no continuous external force applied. This illustrates which concept?
Correct Answer:
Inertia
Explanation:
Inertia is the tendency of an object to keep moving with the same velocity in a straight line unless a net external force acts on it. When there’s no continuous external force on the puck, the net force is essentially zero, so the acceleration is zero and its velocity remains constant. On ice, friction is small, so the puck glides at nearly constant speed in a straight path until something else—like a collision or a hockey stick—acts on it. The other ideas don’t describe this situation as well. Torque would cause rotation if there were a twisting force. Centripetal force is needed to keep an object moving in a circle, which isn’t the case here. Impulse is a short, brief force that changes momentum, not the ongoing absence of force.

What the Course Entails and Exam Details

The AC-HPAT Physics test generally covers core concepts typically taught in high school physics. It is a critical component of the broader HPAT and is essential for admission into health science diplomas. While it's called a 'practice test' article, the content outlined below reflects the real exam's expectations that the practice material will simulate.

The core syllabus frequently includes:

  • Newtonian Mechanics: Concepts like motion (kinematics, dynamics, forces, Newton’s Laws), energy, work, power, and momentum.

  • Electricity & Magnetism: Fundamental principles of electric circuits, charge, potential difference (voltage), current, resistance (Ohm’s Law), and basic magnetic concepts.

  • Waves & Optics: Characteristics of waves, light propagation, reflection, refraction, and lenses.

  • Properties of Matter: Basics of energy transfer, states of matter, and perhaps density.

  • Modern Physics Basics: Depending on the specific program and recent updates, some introductory concepts might be touched upon.

The actual exam details for the physics section are:

  • Format: Typically includes multiple-choice questions designed to test both theoretical understanding and problem-solving abilities.

  • Scoring: Specific passing scores or ideal percentile ranks often depend on the competitive nature of the program you are applying to and the requirements of the administering institution (e.g., Algonquin College).


What to Expect in the Final Exam

While you are studying for a practice test, your ultimate goal is the final AC-HPAT Physics section on exam day.

Expect a structured testing environment, whether on-campus at your chosen college or through an approved virtual proctoring service. The physics section itself will have a specific time limit within the overall AC-HPAT test session, requiring efficient time management. The questions will be varied in difficulty, assessing different facets of the physics syllabus. Note that rules, timing, and passing scores vary by institution and academic year, so it is critical to consult the official details from the specific college where you are applying.


How to Study and Exam Centers

Preparation is paramount for the AC-HPAT. Here are actionable study strategies:

  • Review Core Physics Concepts: Dust off your high school physics textbooks or use online educational resources to refresh your memory on the foundational topics mentioned above. Focus on understanding the formulas and applying them.

  • Utilize High-Quality Practice Tests: Consistently practice with a designated AC-HPAT Physics Practice Test. This is one of the most effective ways to simulate the exam experience, understand the question style, and improve your speed and accuracy.

  • Simulate Test Conditions: When taking practice exams, do so in a quiet room, under timed conditions, and without notes to best replicate the real test day.

  • Identify and Strengthen Weaknesses: Analyze your practice test performance carefully. If you struggle with questions on electricity, dedicate extra study time to that specific area.

  • Master Test-Taking Skills: For multiple-choice questions, practice elimination techniques. If you're stuck, make an educated guess—points are rarely deducted for incorrect answers, but empty spaces certainly don't earn any.

Exam Centers and Access:

  • Official Test Centers: The real AC-HPAT is typically administered directly by the college you are applying to (for example, the Algonquin College Test Centre for their applicants). Check the admission requirements and booking process for the specific institution.

  • Online/Virtual Options: Many institutions now offer secure virtual proctoring options (like Meazure Learning, used by some Algonquin test centers) allowing you to take the exam from a quiet, private location, subject to strict procedural rules.

  • Booking: You will usually be required to book your AC-HPAT appointment through your applicant portal at the relevant college. Be sure to understand deadlines and mandatory academic prerequisites for test registration.


Job Opportunities from the Course

Successfully navigating the AC-HPAT, including the critical physics section, and subsequently graduating from your chosen health program, can unlock diverse and rewarding career paths in the dynamic healthcare sector. Some potential career titles include:

  • Registered Cardiology Technologist (RCT)

  • Medical Radiation Technologist

  • Magnetic Resonance Imaging (MRI) Technologist
