AQA GCSE Trilogy Physics Paper 2 Foundation June 2018 question paper 8464/P/2F

Which of these is a scalar quantity?

Tick one box.

A woman cycled along a straight flat road.

Figure 1 shows how the woman’s velocity changed with time.

Which part of the graph shows the woman moving at constant velocity?

Tick one box.

Which part of the graph shows the woman stationary?

Tick one box.

Between points A and B the woman was accelerating.

Use Figure 1 to determine the total time for which she was accelerating.

Use Figure 1 to determine her increase in velocity between points A and B.

Calculate her acceleration between points A and B.

Use the equation:

Estimate how a typical cycling speed of 6 m/s compares with a typical walking speed.

Tick one box.

Figure 2 shows a slinky spring used to model a sound wave.

Label the arrows on Figure 2

Choose the answers from the box.

What type of wave is a sound wave?

Tick one box.

Figure 3 shows two students measuring the speed of sound in air.

One student bangs two bricks together.

The sound wave produced is reflected from the wall and travels back to the students.

Describe how they can determine the speed of sound.

Figure 4 shows a man doing two stages of a pull up. In both diagrams the man is stationary.

Complete the sentence.

Choose the answer from the box.

upwards force of the bar on the man.

The man has a mass of 85 kg

Gravitational field strength = 9.8 N/kg

Calculate the weight of the man.

Use the equation:

weight = mass × gravitational field strength

The man raises his body a vertical distance of 0.63 m to go from stage 1 to stage 2

Calculate the work done by the man.

Use your answer to question 03.2

Use the equation:

work done = force × distance

The man was not moving at stage 2 How much work is done by the man at stage 2?

A woman uses the bar to do a pull up.

The woman has a mass of 62 kg

Calculate the resultant force on the woman.

Use the equation:

force = mass × acceleration

Figure 5 shows types of waves within the electromagnetic spectrum.

Some of the types of waves are represented by letters.

Which letter shows the position of ultraviolet (UV) radiation within the electromagnetic spectrum?

Tick one box.

A special lamp can produce UV radiation.

Which two statements describe the electromagnetic waves emitted by a UV lamp?

Tick two boxes.

UV radiation is used to treat a vitamin D deficiency.

People should not use a UV lamp for long periods of time.

State two risks of exposure to high levels of UV radiation.

Ionising radiation is used for some medical imaging.

Name two types of electromagnetic waves that are used.

Figure 6 shows a man using a resistance band when exercising.

The resistance band behaves elastically.

What happens to the store of elastic potential energy of the resistance band when the band is stretched?

Explain what happens to the resistance band as it is released.

Figure 7 shows how the extension of the resistance band changes as the force applied changes.

Describe the trend shown in the graph.

Figure 8 shows a chest expander.

Sketch a graph on Figure 9 to show how the extension of a spring in the chest expander changes as the force applied changes.

When a force is applied to a spring, the spring extends by 7.5 cm

Write down the equation that links extension, force and spring constant.

Calculate the force applied to the spring.

The spring has a spring constant of 1 600 N/m

Use your equation from question 05.5

Figure 10 shows a lorry.

The brakes of the lorry are in a poor condition.

What effect will the condition of the brakes have on thinking distance and the braking distance of the lorry?

Thinking distance

Using a hand-held mobile phone while driving is illegal in the United Kingdom.

Table 1 shows the effect of using a mobile phone on thinking distance.

Explain why driving while using a hand-held mobile phone is more dangerous than using a mobile phone with a hands-free kit.

Use data from Table 1

A student investigated acceleration using gliders, an air track and light gates.

The air track reduces friction between the glider and the track to zero.

Figure 11 shows the apparatus.

The glider was released from rest and moved along the track.

The mass holder hit the ground before the card passed through the second light gate.

Which two statements describe the effect this would have on the glider?

Tick two boxes.

The mass holder should not hit the ground before the card passes through the second light gate.

Suggest one way that the student could stop this happening.

The student increased the resultant force acting on the glider by adding more masses to the mass holder.

She calculated the acceleration of the glider for each resultant force.

Each test was done three times.

Table 2 shows the results.

The student made two mistakes in the mean acceleration column.

Identify the mistakes the student made.

Suggest how each mistake can be corrected.

Write a conclusion for this investigation.

Use the data in Table 2

The student used a constant resultant force to accelerate the glider.

The student changed the mass of the glider and calculated the new acceleration.

She repeated this for different masses of the glider, keeping the resultant force constant.

The results are shown in Table 3

Plot the results on Figure 12

Draw a line of best fit.

Describe the relationship between mass and acceleration.

A magnet produces a magnetic field.

Which diagram shows the magnetic field pattern around a bar magnet?

Tick one box.

Figure 13 shows three metal blocks.

The blocks are not labelled.

One block is a permanent magnet, one is iron and one is aluminium.

Describe how another permanent magnet can be used to identify the blocks.

Figure 14 shows a toy crane.

The toy crane uses an electromagnet to pick up and move the blocks.

Explain how this electromagnet is able to pick up and move the blocks.
