Figure 1 shows a skydiver jumping from an aeroplane.

The skydiver is accelerating downwards.

Which force causes the skydiver to accelerate?

Tick () one box.

Which force increases as the skydiver accelerates?

Tick () one box.

Figure 2 shows the two forces acting on the skydiver a few seconds after jumping from the aeroplane.

Calculate the resultant force acting on the skydiver in Figure 2.

Eventually the skydiver stops accelerating and falls at a constant velocity.

What is the resultant force acting on the skydiver when falling at a constant velocity?

Tick () one box.

What name is given to the constant velocity of the skydiver?

Tick () one box.

Figure 3 shows a velocity–time graph for the skydiver.

How many seconds did the skydiver accelerate for?

Use Figure 3.

What was the constant velocity of the skydiver?

Use Figure 3.

After opening a parachute, the skydiver fell at a constant speed of 3.6 m/s for 25 seconds.

Calculate the distance travelled by the skydiver during this time.

Use the equation:

distance travelled = speed × time

Figure 4 shows a person using a newtonmeter to measure the weight of a suitcase.

There is a pair of forces acting between the suitcase and the newtonmeter.

How does the force on the suitcase compare with the force on the newtonmeter?

Tick () one box.

Which sentence describes the directions in which the pair of forces act?

Tick () one box.

What is the weight of the suitcase shown on the newtonmeter in Figure 4 ?

Calculate the mass of the suitcase.

gravitational field strength = 9.8 N/kg

Use your answer from Question 02.3 and the equation:

The suitcase is loaded into an aeroplane. The aeroplane takes off and its height above the ground increases. The aeroplane then flies at a constant height.

Figure 5 shows how the gravitational field strength in the aeroplane varies for the first 25 minutes of the flight.

Describe how the weight of the suitcase will change during the first 25 minutes of the flight.

Use Figure 5.

Figure 6 shows an electronic whistle used by a referee in a football match.

When the button is pressed the whistle emits sound waves that travel through the air.

What is transferred by the sound waves as they travel through the air?

Tick () one box.

What is a typical value for the speed of sound in air?

Tick () one box.

The whistle can emit two different sound waves, A and B.

Figure 7 shows the two different sound waves as displayed on a screen.

The sound waves are drawn to the same scale.

Complete the sentences to describe a difference and a similarity between the two waves.

Choose answers from the box.

Wave A has a frequency of 4.0 kHz.

Which of the following is the same as 4.0 kHz?

Tick () one box.

Calculate the period of wave A.

Use your answer from Question 03.4 and the equation:

Sound waves in air are longitudinal waves.

Complete the sentence to describe a sound wave.

Choose answers from the box.

When sound waves travel through air they create areas

Figure 8 shows a permanent magnet and two magnetic compasses.

The poles of the magnet are labelled X and Y.

The direction of the compass needle in compass A is shown.

Give the names of the poles labelled X and Y in Figure 8.

Draw an arrow on compass B in Figure 8 to show the direction of the magnetic field at that position.

Figure 9 shows security tags on some clothes in a shop.

Security tags can be detected if clothes are taken out of the shop with tags still attached.

The tags are attached to the clothes by pins made from a magnetic material.

A shop assistant can use a magnet to remove the pins.

Which of the following are magnetic materials?

Tick () two boxes.

Which of the following describes the force between a magnetic material and a magnet?

Tick () one box.

The shop assistant removes a security tag and drops the tag into a collecting bin.

As it falls, the tag accelerates at 9.8 m/s².

The mass of the tag is 0.030 kg.

Calculate the resultant force acting on the tag.

Use the equation:

resultant force = mass × acceleration

The stopping distance of a car depends on the thinking distance and the braking distance.

Which of the following affects the thinking distance?

Tick () one box.

A car manufacturer tested three different types of tyre which were fitted to three identical cars.

This is the method used.

1. Drive the car along a road.

2. Apply the brakes until the car stops.

3. Measure the distance travelled while braking.

4. Repeat steps 1 to 3 for each car when the road is dry and when the road

is wet.

The brakes were applied with the same force for each test.

Give one other variable that should have been kept the same for each test.

Figure 10 shows the results.

The manufacturer wants to put the safest tyres on a new car.

Evaluate the safety of each type of tyre.

Use data from Figure 10.

When the brakes are applied, a force does work to stop the car.

Use the Physics Equations Sheet to answer questions 05.4 and 05.5.

Write down the equation that links distance (s), force (F) and work done (W).

The braking force acting on a car is 6000 N.

The work done to stop the car is 300 000 J.

Calculate the braking distance of the car.

Explain how the force applied by the brakes affects the braking distance of the car.

A teacher demonstrated how the frequency of a wave on a string affects the wavelength of the wave.

Figure 11 shows the equipment used.

The frequency of the signal generator is adjusted so that the wave shown in Figure 11 is seen.

At this frequency the string vibrates between the two positions shown in Figure 11.

Describe a method the teacher could use to investigate how the frequency of the wave affects the wavelength.

Use the Physics Equations Sheet to answer questions 06.2 and 06.3.

Which equation links frequency (f), wavelength (λ) and wave speed (v)?

Tick () one box.

The wave on the string has a frequency of 45.0 Hz.

The wave speed is 35.1 m/s.

Calculate the wavelength of the wave.

Figure 12 shows an Olympic gymnast performing a floor routine.

The floor contains springs.

When the gymnast lands on the floor, a force compresses the springs in the floor.

When a spring is compressed, the elastic potential energy of the spring increases.

Explain why compressing the springs in the floor helps the gymnast to jump higher.

Use ideas about energy in your answer.

When the gymnast lands on the floor, one of the springs compresses by 1.2 cm.

spring constant = 8500 N/m

Calculate the elastic potential energy stored in the spring.

Use the Physics Equations Sheet.

Give the unit.

A student investigated a spring with a different spring constant.

When masses are placed on the spring it compresses.

The student measured the compression of the spring for different masses.

Figure 13 shows some of the equipment used.

Describe how the compression of the spring could be determined.

Explain why the investigation should be done on the laboratory floor rather than on a table.

Figure 14 shows the results.

The spring constant is the gradient of the line of best fit shown on Figure 14.

Determine the value Δ y on Figure 14.

Determine the value Δ x on Figure 14.

Determine the spring constant of the spring.
