Sample GCSE Physics Exam Questions and Explanations

Question 1: Force and Motion

Question: An object of mass 2 kg is accelerating at 3 m/s². What is the force acting on it?

Answer: 6 N.

Explanation: Force (F) can be calculated using Newton’s second law of motion, which states that Force equals mass (m) times acceleration (a), or F = m*a. So, 2 kg * 3 m/s² equals 6 N.

Common Mistake: Students often forget to apply Newton’s second law correctly or mix up the units.

Question 2: Energy

Question: What type of energy is stored in a stretched spring?

Answer: Elastic potential energy.

Explanation: When a spring is stretched or compressed, it stores elastic potential energy. This energy can be released when the spring is allowed to return to its original shape.

Common Mistake: Confusing different types of potential energy – gravitational, chemical, and elastic.

Question 3: Waves

Question: What is the term for the bending of waves around obstacles?

Answer: Diffraction.

Explanation: Diffraction is the phenomenon of waves bending around obstacles or spreading out after passing through narrow openings. It occurs with all types of waves, including light, sound, and water waves.

Common Mistake: Students often confuse diffraction with refraction, which is the bending of waves due to a change in speed when moving from one medium to another.

Question 4: Electricity and Magnetism

Question: In an electrical circuit, what component is used to measure current?

Answer: Ammeter.

Explanation: An ammeter is an instrument used in a circuit to measure electric current. It is always connected in series with the component of interest.

Common Mistake: Students sometimes confuse an ammeter with a voltmeter, which is used to measure potential difference (voltage) and is connected in parallel.

Question 5: Atomic Structure

Question: What are isotopes?

Answer: Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons.

Explanation: The atomic number (number of protons) defines an element, but the number of neutrons can vary, creating isotopes. This difference in neutron number results in isotopes of the same element having different atomic masses.

Common Mistake: Many students mistake isotopes for ions, which are atoms with an unequal number of protons and electrons, thus bearing a charge. Isotopes, on the other hand, are neutral.

Overview of the GCSE Physics Marking Scheme

The GCSE Physics marking scheme is a vital resource for understanding how examiners grade student responses. It details the allocation of marks for each question and provides insight into what constitutes a high-quality answer.

Component Breakdown

2. Structured Questions – These include short answer questions, extended response questions, and practical-based questions. The number of marks varies based on the complexity and depth of the question.

Mark Allocation

Each question in the exam paper indicates the number of marks available. Simple, direct questions may be worth one mark, while more complex questions requiring longer, detailed responses can be worth several marks.

Quality of Written Communication

For questions involving extended writing, some marks are often allocated for the quality of written communication. This includes clarity of expression, the structure of arguments, and the presentation of information, mathematical calculations, and diagrams.

Practical Skills Assessment

Given the significant emphasis on practical skills in GCSE Physics, certain questions are specifically designed to assess these skills. These questions can cover areas such as the ability to select and use appropriate equipment, make accurate observations, handle data, and interpret experimental results.

Understanding the GCSE Physics marking scheme can help parents guide their children in exam technique and preparation, ensuring they know where to focus their efforts and how to best structure their answers.
