A student places a trolley at the top of a runway, as shown in Figure 1.

The student had to lift the trolley through a height of 26 cm to put it at the top of the runway.

The gravitational potential energy, Δ GPE, of the trolley increases by 4.1 J when lifted to the top of the runway.

The gravitational field strength, g, = 10 N / kg.

Show that the mass of the trolley is about 1.6 kg.

Use the equation

The student releases the trolley and the trolley moves down the runway.

The student assumes that all the extra gravitational potential energy, ∆ GPE, stored at the top of the runway is transferred to kinetic energy at the end of the runway.

Calculate the expected value of the velocity of the trolley at the end of the runway.

Use the equation

expected velocity =_........

The light gate, shown in Figure 1, is used to determine the actual velocity of the trolley at the end of the runway.

The actual velocity at the end of the runway is less than the expected velocity as calculated in (ii).

Suggest one way to reduce the difference between the actual velocity and the expected velocity.

A different student finds out how much power can be generated by running up some stairs in a measured amount of time.

The following quantities are measured:

mass of student = 48 kg

total height of stairs = 2.9 m

time to run up stairs = 3.4 s

Calculate the power the student generated.

Give the answer to 2 significant figures (2 s.f.).

Use the equation

State the frequency of the supply of electricity to homes in the UK (United Kingdom).

The mains supply to the television is 230 V.

The current supplied to the television is 0.53 A.

Calculate the power input to the television.

Use the equation

P = I × V

A plug connects a television to the mains supply.

The plug contains a fuse that is connected to the

A 3 A fuse is used in the plug.

Explain what happens if a fault causes the current to rise to more than 3 A.

A fuse is a safety device.

State one other safety device that can be used in domestic electrical wiring.

Figure 2 shows two pieces of electrical cable side by side.

Cable 1 is used to supply electric current to the television.

Cable 2 is used to supply electric current to the house.

Explain why cable 2 is more suitable than cable 1 for supplying electric current to the house.

A teacher heats a block of wax until all the wax melts.

The teacher pours the melted wax into a container and allows the wax to cool.

Figure 3 shows how the temperature of the wax changes during a time of 20 minutes.

Four different points on the graph are labelled P, Q, R and S.

Between which two points is all the wax liquid?

Describe the change in the motion of the wax particles as the wax changes from liquid to solid.

Figure 4 shows the values of some properties of the wax.

The wax has a mass of 3.9 kg.

Using information from Figure 4, calculate the volume of the wax when it is all liquid.

Use the equation

volume =_........ ³

State, using information from Figure 4, how the volume of the wax changes when it becomes a solid.

Explain why, using Figure 4, the time from R to S is much shorter than the time from Q to R on the graph in Figure 3.

Figure 5 shows two nails, X and Y, hanging from a magnet.

Complete the labels in Figure 5 to show the N and S poles of nail Y.

Nail X is removed from the magnet and nail Y falls off nail X.

This shows that the magnet caused both nails to be

A teacher has a pile of steel nails, a magnet and some plastic strips that are all the same size.

The teacher places a plastic strip under the magnet and picks up some nails from the pile, as shown in Figure 6.

Some nails are not picked up and are left behind on the bench.

The teacher investigates how the number of nails that can be picked up changes when the number of plastic strips under the magnet is increased.

The results are shown in Figure 7.

Complete Figure 7 to show the missing value.

Use the data in Figure 7 to complete the bar chart in Figure 8.

Use Figure 8 to describe the relationship between the number of plastic strips and the mean number of nails picked up.

A student thinks that none of the nails used in the investigation become permanently magnetised.

Suggest how the student could test this hypothesis.

The magnetic flux density, B, is a measure of the strength of the magnetic field of a magnet.

B varies with the distance, d, from a magnetic pole of a magnet as given by the equation

where K is a constant for the magnet.

At a distance of 3 mm from the pole of a magnet, B = 650 μ T.

Calculate the value of B at a distance of 6 mm from the pole of the magnet.

B at 6 mm =_........

A student measures the length of a spring when it is horizontal and when it is vertical, as shown in Figures 9a and 9b.

The length, Y, of the vertical spring in Figure 9b is greater than the length, X, of the horizontal spring in Figure 9a.

Give a reason why the length of the spring in Figure 9b is greater than the length of the the spring in Figure 9a.

The student adds some weights to the end of the spring, as shown in Figure 10b.

(Source: https://www.shalom-education.com/courses/ks3-physics/lessons/motion-and-forces/topic/deformation-and-hookes-law/)

The extension of the spring due to these added weights is equal to

The extension of the spring in Figure 10b is now determined for different weights added to the spring up to a maximum of 6 N.

Figure 11 shows a graph of the results.

The increase in potential energy stored in the spring is equal to the area under the graph in Figure 11.

Calculate the increase in potential energy stored in the spring when the spring is extended from 0 cm to 8 cm.

Give your answer in joules (J).

Calculate the spring constant of the spring using data from the graph in Figure 11.

Figure 13 shows two forces, P and Q, acting at point X.

A student connects a resistor across the terminals of a 9 V battery.

There is a current of 6 mA in the resistor.

Calculate the resistance of the resistor.

Describe how an additional component could be used to vary the current in the resistor.

A voltmeter has four different scales.

Which one of these scales would be most suitable to measure a voltage of 0.85 V?

Describe how a student can use ammeters and voltmeters to investigate the information given in Figure 14.

Your answer should include

• a comparison of the results that would be expected
