Which row describes the motion of the car at point X and at point Y?
A heavy metal ball falls vertically downwards through air past four equally spaced levels J, K, L and M.
The times taken to fall from one level to the next are measured.
Where is the speed of the ball greatest and which time is shortest?
An object which has a mass of 600 kg is on the planet Mars.
The acceleration due to gravity on Mars is $4.0 \, \text{m/s}^2$.
What is the weight of the object on Mars?
Two objects are placed on a balance, one on each side:
Which properties of the objects can be compared using the balance?
X, Y and Z are three regularly shaped solid objects. Their dimensions and masses are shown in the diagrams. Which objects have the same density?
A car is driven from rest on a long straight road. The car engine exerts a constant driving force.
The diagram shows the horizontal forces acting on the car. The resistive forces are proportional to the speed of the car.
Why does the car eventually reach a maximum speed?
A spring is suspended from a stand. Loads are added and the extensions are measured.
Which graph shows the result of plotting extension against load?
A wooden bar is pivoted at its centre so that it can rotate freely. Two equal forces $F$ are applied to the bar.
In which diagram is the turning effect greatest?
A machine is very efficient. What does this mean?
A body is lifted against gravity.
Which equation shows the work done on the body?
The diagram shows a simple mercury barometer.
A change is made and the vertical height $h$ of the column increases.
Which change causes this increase?
The diagram shows a stone suspended on a string under the surface of a liquid. The stone experiences a pressure caused by the liquid.
What would increase the pressure on the stone?
Which statement is correct?
On a hot summer day, the level of the water in a pond falls. Which statement explains this?
Here are three statements about a liquid-in-glass thermometer with a Celsius scale.
1. The lower fixed point is the temperature at which pure water freezes.
2. The upper fixed point is the temperature at which pure water boils.
3. A scale is made by dividing the distance between the fixed points into equal divisions.
Which statements are correct?
A night storage heater contains a large block of material that is heated electrically during the night. During the day the block cools down, releasing thermal energy into the room.
Which thermal capacity and which night-time temperature increase will cause the most energy to be stored by the block?
A student investigates the melting point of a pure substance. She heats the substance slowly and takes readings of its temperature as the substance starts to melt and when it finishes melting. Which statement is correct?
A person holds an empty glass beaker and pours hot water into it. Why does it take a few seconds before his hand starts to feel hot?
The metal surface of a kettle is hot.
What happens to the cool air outside the kettle when it comes into contact with the hot kettle?
A student draws a diagram to show two different properties of a water wave. The arrows show the wave directions.
Which two wave properties does the diagram show?
The diagram shows a cork with a weight attached so that the cork floats upright in water.
Transverse waves travel across the water from X to Y.
In which direction do the waves make the cork move?
A student draws a ray diagram to show how a ray of light is reflected by a number of mirrors.
Which reflection has not been drawn correctly?
Light passes through a glass block.
What is the path of the light?
The diagram shows radiation from a lamp passing through a prism.
Which type of radiation is found at P?
A pulse of sound is produced at the bottom of a boat. The sound travels through the water and is reflected from a shoal of fish. The sound reaches the boat again after 1.2 s. The speed of sound in the water is 1500 m/s. How far below the bottom of the boat is the shoal of fish?
Which statement about ultrasound is correct?
A metal bar is placed inside a current-carrying coil, as shown in diagram 1.
There is a small current in the coil. The bar holds a few nails, as shown in diagram 2.
When there is no current in the coil, the nails drop off.
Which row is correct?
[Table_1]
An iron ball on a horizontal wooden table rolls near the north pole of a bar magnet which is lying on the table.
Which diagram shows the most likely path of the ball, as seen from above the table?
Diagram 1 shows two thin, uncharged strips of plastic.
Diagram 2 shows the same strips after they have been rubbed with a dry cloth.
Which row describes the charge on the strips after rubbing, and the force between the strips after rubbing?
A battery stores chemical potential energy. The battery is connected to a resistor.
As the battery runs down, what happens to its chemical energy?
[Table_1]
The diagram shows a circuit including a lamp, an electric bell and three switches $S_1$, $S_2$ and $S_3$.
The lamp and bell are not faulty.
The bell is ringing but the lamp is not lit.
Which switches are closed?
A student is designing a lighting circuit for a dolls’ house. He sets up two different circuits.
Each circuit contains a 12 V power supply and three identical lamps.
Each lamp is designed to operate at normal brightness when connected individually to a 12 V supply.
Which statement is correct?
A lamp is to be connected in a circuit so that the potential difference (p.d.) across it can be varied from 0 to 6V.
Which circuit would be most suitable?
A simple wiring diagram for an electric cooker is shown. Why is there a wire connecting the metal case of the cooker to earth?
In an experiment, a wire is held above a compass needle as shown.
An electric current is switched on in the wire and the compass needle is deflected.
Which row explains why this happens and then describes what happens when the current is reversed?
Which device relies upon the magnetic effect of an electric current?
