AQA GCSE Trilogy Physics Paper 2 Foundation June 2023 question paper 8464/P/2F

Figure 1 shows a garden chair hanging from a spring.

The weight of the person causes the spring to extend.

Why does the weight of the person cause the spring to extend? Tick (✓) one box.

Complete the sentence. Choose the answer from the box.

The weight of the person in Figure 1 is force.

The weight of the person causes an extension in the spring of 0.070 m.

The spring constant of the spring is 12 000 N/m.

Calculate the weight of the person. Use the equation: weight = spring constant × extension

Calculate the elastic potential energy stored in the extended spring. Use the equation: elastic potential energy = 0.5 × spring constant × (extension)²

If there is more than one person on the chair, the spring could become inelastically deformed. What is meant by ‘inelastically deformed’? Tick (✓) one box.

The manufacturer of the chair investigated the extension of a new spring.

Figure 2 shows slotted masses hanging from the spring. The weight of the masses extends the spring.

Which length in Figure 2 represents the extension of the spring? Tick (✓) one box.

Which graph shows that the extension of the spring is directly proportional to the force applied to the spring? Tick (✓) one box.

Table 1 shows the results of the manufacturer’s investigation.

Suggest two improvements to the investigation.

A car contains a device called a black box. The black box records the distance travelled and the time taken for each journey. Figure 3 shows the distance–time graph for part of a journey.

Which feature of Figure 3 shows that the car travels at a constant speed for the first 4 seconds? Tick (✓) one box.

After 4 seconds the driver applied the brakes and the car slowed down and stopped. The distance the car travelled after the brakes were applied is called the braking distance. Determine the braking distance of the car. Use Figure 3.

The black box also records the deceleration of the car.

As the car decelerates, the velocity of the car changes by 16 m/s. The car decelerates for 2.5 seconds. Calculate the deceleration of the car. Use the equation:

If the black box records large decelerations, it identifies that the driving may be dangerous. Why can large decelerations be dangerous? Tick (✓) two boxes.

The black box monitors the speed of the car. Describe how speed affects braking distance.

Figure 4 shows iron filings sprinkled around a bar magnet.

Why are the iron filings attracted to the bar magnet? Tick (✓) one box.

Figure 5 shows a bar magnet. Draw magnetic field lines to show the magnetic field pattern around the bar magnet. You should add arrows to the field lines to show the direction of the magnetic field.

Figure 5

Figure 6 shows two bar magnets.

Figure 6

The magnets attract each other. What conclusion can be made about the two poles marked X and Y ? Tick (✓) one box.

Figure 7 shows some plotting compasses around a wire. There is no current in

the wire.

Why do the plotting compasses all point in the same direction?

When the switch is closed there is a current in the wire. The current creates a magnetic field. What shape are the magnetic field lines around the wire? Tick (✓) one box.

A student investigated the force exerted by an electromagnet on a paper clip.

The student varied the distance between the paper clip and the electromagnet. Figure 8 shows the equipment used.

The student recorded the reading on the newtonmeter for several different distances.

The current in the electromagnet was the same for each distance. Complete the sentence. Choose the answer from the box.

In the investigation, the current was variable.

What is the size of the downward force on the paper clip in Figure 8 ?

The distance between the paper clip and the electromagnet is increased. What happens to the size of the downward force?

Sound waves are longitudinal waves.

Figure 9 shows a sound wave.

Complete the labels on Figure 9. Choose answers from the box.

Which of the following is true for longitudinal waves? Tick (✓) one box.

Figure 10 shows a device a farmer uses to scare away birds.

The device emits a very loud sound. The farmer measures the sound emitted by the device at different distances from the device.

Figure 11 shows a visual display of the sound waves at different distances from the device. Both waves are drawn to the same scale.

Which property of the wave changes between 80 m and 200 m? Tick (✓) one box.

Figure 12 shows how the speed of the sound emitted by the device is affected by the

temperature of the air.

The farmer tests the device on a day when the temperature of the air is 15 °C. What is the speed of the sound emitted by the device when the temperature of the air is 15 °C?

The farmer stands a safe distance from the device. It takes a time of 0.20 s for the sound to travel from the device to the farmer. Calculate the distance between the device and the farmer. Use your answer to Question 04.4 and the equation: distance = speed × time

Explain how the time taken for the sound to reach the farmer is affected by the temperature of the air. Use Figure 12.

Figure 13 shows an engineer climbing up a ladder.

The distance between each rung on the ladder is 30 cm.

What is 30 cm in metres? Tick (✓) one box.

The engineer has a weight of 710 N. Calculate the work done when climbing up one rung of the ladder. Use your answer to Question 05.1 and the equation: work done = force × distance

The engineer climbs the ladder carrying some equipment. Give the reason why carrying equipment increases the work done by the engineer when climbing the ladder.

The engineer is stationary at the top of the ladder. Which energy stores of the engineer increase due to the engineer climbing the ladder? Tick (✓) two boxes.

Use the Physics Equations Sheet to answer questions 05.5 and 05.6.

Write down the equation that links gravitational field strength (g), mass (m) and weight (W).

The engineer has a weight of 710 N. gravitational field strength = 9.8 N/kg Calculate the mass of the engineer. Give your answer to 2 significant figures.

The Sun emits a continuous spectrum of electromagnetic waves. Figure 14 names some of the groups of waves in the electromagnetic spectrum.

Name groups A, B and C in Figure 14.

Give one similarity and one difference between the properties of ultraviolet waves and gamma rays.

Figure 15 shows white light split into a spectrum of different colours by a glass prism.

Light changes direction when it enters the glass prism. What name is given to this process?

Use the Physics Equations Sheet to answer questions 06.4 and 06.5.

Write down the equation that links frequency (f), wavelength (λ) and wave speed (v).

The wave in the middle of the spectrum has a wavelength of 5.0 × 10^–7 m. wave speed of light = 3.0 × 10⁸ m/s Calculate the frequency of the wave.

A student investigated how the acceleration of a trolley is affected by the force acting on the trolley. Figure 16 shows some of the equipment used.

Describe a method the student could use. Your answer should include any extra equipment needed.

Table 2 shows one set of results for a similar investigation.

Which of Newton’s laws predicts that the acceleration of the trolley is proportional to the resultant force on the trolley? Tick (✓) one box.

Determine the acceleration of the trolley when the resultant force is 3.6 N. Use Table 2.

Use the Physics Equations Sheet to answer questions 07.4 and 07.5.
