CRCR FINAL TEST 2026 QUESTIONS
WITH CORRECT ANSWERS GRADED
A+
◍ Which quantities have magnitude or size only?.
Answer: Scalar
◍ What are the properties of vector quantities?.
Answer: They have magnitude and an associated direction
◍ How can you represent a vector quantity using a symbol?.
Answer: With an arrow where the length of the arrow represents the
magnitude, and the direction of the arrow the direction of the vector quantity
◍ What is a force?.
Answer: A push or pull that acts on an object due the interaction of another
object
◍ Grade 9 structure for any 6-mark physics question.
Answer: Begin with a clear statement answering the question. Explain the
physics step by step using correct scientific vocabulary. Include equations or
proportional relationships where relevant. Link cause to effect throughout.
Finish with a concluding sentence that directly answers the question.
◍ What AQA examiners look for in 6-mark answers.
Answer: Correct physics ideas, clear logical structure, cause-and-effect
explanations, use of equations or data where appropriate, and correct
scientific terminology written in full sentences.
◍ What is a contact force?.
Answer: A force that acts between two objects that are physically touching
each other
,◍ Common mistakes in 6-mark questions.
Answer: Listing facts without explanation, missing equations, not linking
ideas together, contradicting physics principles, or failing to answer the
question directly.
◍ Name four contact forces.
Answer: Friction, air resistance, tension and normal
◍ What is Newton's Third Law of motion?.
Answer: When a contact force acts between two objects, both objects
experience the same size force, but in opposite directions
◍ Memory aid for 6-mark answers.
Answer: PEEL - Point, Explain, Evidence (equation or data), Link back to
the question.
◍ What is a non-contact force?.
Answer: Non-contact forces are forces that act between two objects that are
not physically touching each other
◍ How to investigate waves on a string.
Answer: Attach a string to a signal generator and pass it over a pulley with a
hanging mass to keep tension constant. Change the frequency using the
signal generator and observe the wave pattern.
◍ Control variables in a wave experiment.
Answer: Tension in the string, length of string, and material of the string
must be kept constant so only frequency affects wavelength.
◍ How to measure wavelength accurately.
Answer: Measure the distance across several complete waves and divide by
the number of waves to reduce uncertainty.
◍ Wave equation.
Answer: Wave speed = frequency × wavelength (v = fλ).
◍ Name three non-contact forces.
Answer: Gravitational force, electrostatic force and magnetic force
,◍ What is weight?.
Answer: The force acting on an object due to gravity
◍ How to calculate wavelength.
Answer: Rearrange the wave equation to λ = v ÷ f. Substitute values and
include units in metres.
◍ What does the weight of an object depend on?.
Answer: The gravitational field strength at the point where the object is
◍ Common mistake in wave calculations.
Answer: Forgetting to rearrange the equation correctly or using incorrect
units.
◍ What is the equation that links weight, mass and gravitational field
strength?.
Answer: Weight = mass x gravitational field strength if [W=mg]
◍ What is the relationship between the mass of an object and its gravitational
field?.
Answer: The more mass an object has the greater its gravitational field
◍ Grade 9 model answer - waves on a string method.
Answer: The string is connected to a signal generator and passed over a
pulley with a mass to maintain constant tension. The frequency is changed
using the signal generator while keeping tension and string length constant.
For each frequency, the wavelength is measured by measuring several
waves and dividing to reduce uncertainty. The measurements are repeated
and a mean calculated to improve reliability.
◍ What is the unit of gravitational field strength?.
Answer: Newtons per kg [N/kg]
◍ What is the unit of weight?.
Answer: Newtons (N)
◍ What is the unit of mass?.
Answer: Kilograms (kg)
, ◍ Elastic potential energy equation.
Answer: Elastic potential energy = ½ × spring constant × extension² (E =
½ke²).
◍ What is the 'centre of mass' of an object?.
Answer: A single point in an object where the weight may be considered to
act
◍ Units for elastic potential energy.
Answer: Joules (J).
◍ How do you measure weight?.
Answer: Using a calibrated spring-balance (a newtonmeter)
◍ Why extension must be in metres.
Answer: The equation requires SI units; using centimetres gives an incorrect
answer.
◍ What's the relationship between the weight and the mass of an object?.
Answer: They are directly proportional
◍ Energy transfer in a sprung gym floor.
Answer: Kinetic energy is transferred into elastic potential energy as the
springs compress, then transferred back into kinetic energy as the springs
decompress.
◍ What is a resultant force?.
Answer: A single force that replaces a number of forces acting on an object
that has the same effect as all of the original forces acting together
◍ When does a force do work on an object?.
Answer: When the force causes a displacement of the object
◍ Grade 9 model answer - elastic energy in springs.
Answer: When the gymnast lands, kinetic energy is transferred to elastic
potential energy as the springs compress. According to E = ½ke², greater
compression stores more energy. As the springs return to their original
shape, energy is transferred back into kinetic energy, increasing upward
