1A car moves along a straight road with a constant acceleration of 2.5 m/s². If the car starts from rest, what is its velocity after 6.0 s?

A.7.5 m/s

B.30 m/s

C.45 m/s

D.15 m/s

Explanation: For uniformly accelerated motion from rest, v = v0 + a t = 0 + 2.5 × 6.0 = 15 m/s.

2A stone is dropped from rest from the top of a vertical cliff and strikes the ground 4.0 s later. Neglecting air resistance and taking g = 9.8 m/s², what is the height of the cliff?

A.39.2 m

B.156.8 m

C.19.6 m

D.78.4 m

Explanation: In free fall from rest (v0 = 0), vertical displacement is given by y = (1/2) * g * t². Substituting the parameters gives y = 0.5 * 9.8 m/s² * (4.0 s)² = 4.9 * 16 = 78.4 m. The displacement is proportional to the square of the elapsed time under constant gravitational acceleration.

3A block of mass 5.0 kg rests on a horizontal surface. A horizontal pulling force of 20 N is applied to the right while a constant kinetic friction force of 5.0 N opposes the motion. What is the magnitude of the block's acceleration?

A.1.0 m/s²

B.4.0 m/s²

C.5.0 m/s²

D.3.0 m/s²

Explanation: According to Newton's second law, the net horizontal force determines acceleration: F_net = F_pull - F_friction = 20 N - 5.0 N = 15 N. Then a = F_net / m = 15 N / 5.0 kg = 3.0 m/s². The frictional force reduces the effective accelerating force acting on the mass.

4A 2.0 kg block slides down a plane inclined at 30° to the horizontal. A friction force of 3.4 N acts on it. What is the magnitude of its acceleration? (g = 9.8 m s⁻², sin 30° = 0.50)

A.3.2 m/s²

B.4.9 m/s²

C.6.6 m/s²

D.1.7 m/s²

Explanation: The component of the weight along the plane is m g sin 30° = 2.0 × 9.8 × 0.50 = 9.8 N. The resultant force along the plane is 9.8 − 3.4 = 6.4 N, so a = 6.4 / 2.0 = 3.2 m/s².

5According to Newton's third law of motion, which statement correctly describes an action-reaction pair of forces?

A.The forces act on two different bodies and have equal magnitude but opposite directions.

B.The forces act on the same body and cancel each other out to produce equilibrium.

C.The action force occurs before the reaction force with a slight time delay.

D.The action force is always greater in magnitude than the reaction force during acceleration.

Explanation: Newton's third law states that whenever body A exerts a force on body B, body B simultaneously exerts a force on body A of equal magnitude and opposite direction. Because the two forces act on different bodies, they never cancel each other out in the equation of motion of a single object.

6A ball is launched vertically upward with an initial speed of 19.6 m/s from ground level. Taking g = 9.8 m/s² and neglecting air resistance, what is the maximum height reached by the ball?

A.19.6 m

B.9.8 m

C.2.0 m

D.39.2 m

Explanation: At the highest point the velocity is zero. By conservation of mechanical energy (or v² = v0² − 2 g h): h = v0² / (2 g) = 19.6² / (2 × 9.8) = 19.6 m. Equivalently, the ball takes t = v0 / g = 2.0 s to reach the top, and h = v0 t − ½ g t² = 39.2 − 19.6 = 19.6 m.

7A car goes round a roundabout of radius 20 m at a constant speed of 10 m/s. What is the magnitude of its acceleration?

A.0 m/s²

B.0.50 m/s²

C.2.0 m/s²

D.5.0 m/s²

Explanation: In uniform circular motion the speed is constant but the direction of the velocity changes, so there is a centripetal acceleration: a = v² / r = 10² / 20 = 5.0 m/s², directed towards the centre.

8The 1D position of a particle moving along the x-axis is given by x(t) = 4.0 + 3.0t - 2.0t² (in SI units). What is the acceleration of the particle at t = 2.0 s?

A.-4.0 m/s²

B.-2.0 m/s²

C.3.0 m/s²

D.-5.0 m/s²

Explanation: Comparing x(t) = 4.0 + 3.0 t − 2.0 t² with x = x0 + v0 t + ½ a t² gives x0 = 4.0 m, v0 = 3.0 m/s and ½ a = −2.0 m/s², so a = −4.0 m/s². The acceleration is constant, so it has this value at t = 2.0 s.

9An elevator cab of mass 800 kg accelerates upward at a constant rate of 1.5 m/s². Taking g = 9.8 m/s², what is the tension in the supporting cable?

A.6640 N

B.7840 N

C.9040 N

D.1200 N

Explanation: Applying Newton's second law in the upward direction: T - m*g = m*a. Rearranging gives T = m*(g + a) = (800 kg)(9.8 m/s² + 1.5 m/s²) = 800 * 11.3 = 9040 N. When accelerating upward, tension must exceed the cab's weight to provide the upward net force.

10A geostationary satellite completes one orbit in about 24 h. What is the magnitude of its angular speed?

A.2.6 × 10⁻¹ rad/s

B.4.4 × 10⁻³ rad/s

C.1.2 × 10⁻⁵ rad/s

D.7.3 × 10⁻⁵ rad/s

Explanation: ω = 2π / T, with T in seconds: T = 24 × 3600 = 86 400 s, so ω = 2π / 86 400 ≈ 7.3 × 10⁻⁵ rad/s. This equals the angular speed of the Earth's rotation, which is why the satellite stays above the same point.

About the Física e Química A (Prova 715) Exam

The Exame Final Nacional de Física e Química A (prova 715) is an 11th-grade national secondary exam in Portugal. Since the 2025 reorganization of the Ministry of Education (Decreto-Lei n.º 105/2025), exam papers are prepared by EduQA — Instituto de Educação, Qualidade e Avaliação, I. P., which succeeded IAVE, and the exams are organized and graded under the Júri Nacional de Exames. Written exam on the Aprendizagens Essenciais of Física e Química A for the 10th and 11th grades, balanced between physics and chemistry and between the two school years; experimental work is assessed. The paper includes a table of constants, a formula sheet and a periodic table. The paper combines selection items (such as multiple choice) and constructed-response items, scored out of 200 points; answers are written on answer sheets that are later digitized. The exam covers energy and its conservation, mechanics, waves and electromagnetism, atoms and the periodic table, bonding and chemical transformations, quantitative aspects, chemical equilibrium and reactions in aqueous systems. It counts towards the subject's final grade and can be used as an admission exam (prova de ingresso) for higher education where a course requires it. This bank is an independent English-language multiple-choice study adaptation with 100 original practice questions. It is not affiliated with EduQA or the JNE and does not reproduce the official paper or its constructed-response tasks.

Física e Química A (Prova 715): Suggested Study Strategy

1Memorize and practice the standard relationships for kinematics, Newton's second law, and conservation of mechanical energy.

2Pay strict attention to significant figures and standard SI units (convert km/h to m/s, cm³ to dm³ or m³, etc.).

3Master the distinction between electronic geometry and molecular geometry using VSEPR theory.

4Practice stoichiometry calculations systematically: convert given masses or volumes to moles before applying stoichiometric ratios.

5Understand Le Chatelier's principle thoroughly: temperature changes alter Kc, whereas concentration and pressure changes shift equilibrium without changing Kc.

6Work through official past papers published by EduQA to get accustomed to the official Portuguese phrasing and scoring rubric.

Frequently Asked Questions

Who prepares and grades the exam?

Since the 2025 reorganization (Decreto-Lei n.º 105/2025), exam papers are prepared by EduQA — Instituto de Educação, Qualidade e Avaliação, I. P., which succeeded IAVE. The exams are run in schools and graded under the Júri Nacional de Exames (JNE).

How is the exam structured?

Is there a pass mark?

No single pass mark: the exam is scored 0–200. For internal students it counts for 25% of the final subject grade (CFD = 0.75 × internal grade + 0.25 × exam); for external candidates the exam grade is the subject grade, so at least 95/200 is needed. When used as an admission exam (prova de ingresso), each higher-education institution sets the minimum, never below 95/200.

How much does it cost?

Free for students in compulsory education who register on time and for internal students in the 1st phase; €3 per exam for 2nd-phase grade improvement, for external candidates (autopropostos) outside compulsory education and for external grade improvement; late registration costs €25 plus €3 per exam (JNE/DGES Guia Geral de Exames 2026).

What reference materials are provided?

The paper includes a table of constants, a formula sheet and a periodic table (Annexes 1–3 of the 2026 Informação-Prova).

How does this practice bank relate to the official exam?

This bank is an independent English-language multiple-choice study adaptation with 100 original practice questions. It is not affiliated with EduQA or the JNE and does not reproduce the official paper or its constructed-response tasks.
