Well Done you passed the test! You’re on your way to getting the grades you want!
Why not try another Science Mock Exam and see how well you do?
Nice try, check your answers to see where you went wrong.
Why not get a bit more practice with some physics quizzes and then come back and have another try!
#1. Iron is a magnetic material – true or false?
#2. Using the equation ρ = m/V, calculate the density of a gold bar that has a mass of 25kg and a volume of 0.0013m³. Answer to 1 decimal place and give your answer in kg/m³. ? The units for density are kg/m³, do not include them in your answer
#3. Is this a parallel or series circuit?
#4. Is this a parallel or series circuit?
#5. Does a current flow if there is no source of potential difference?
#6. Magnets have north and south poles – if two south poles are put close together what will happen?
#7. What is the name of the phase change from solid to liquid?
#8. What is this component?
#9. What is current measured in?
#10. Determine the speed of the object between 1 and 3 seconds. ? answer to 2 decimal places
#11. A student sets up a series circuit that has two filament lamps, a power source and a switch after the first lamp. Can the first lamp be turned off whilst keeping the second lamp on?
#12. Is velocity a vector or a scalar?
#13. Acceleration is an increase in the rate of what?
#14. Complete the equation for power. Power (W) = work done (J) / ……..
#15. Which of the following equations is the correct way to make A the subject of the equation F = MA?
Take a look at this video on rearranging equations if you got this one wrong.
#16. Find the volume of a silver block that has a mass of 159g and a density of 10.49 g/cm³. Give your answer in cm³ and to 1 decimal place.
#17. The equation for work done is E = F x d. Calculate the distance moved when a 650 J of work is done to move a 160 N object. Leave your answer to 1 d.p and include the units. ? Do not include your workings in your answer
#18. The needles of plotting compasses are tiny magnets – they always point near the Earth’s North Pole – why is this?
#19. Are ammeters connected in series or in parallel?
#20. What is the function of a resistor?
#21. What is the function of an LED?
#22. Calculate the distance travelled by the runner in the velocity/time graph.
The area under the graph = distance travelled
Split the graph into triangles and rectangles and calculate the areas. Then add together the areas.
Area of a rectangle = Length x Height
Area of a triangle = 1/2 x Length x Height
90m 120m 180m = 390m
NOTE: the graph starts at one second and not 0. Don’t be fooled, look at the axes carefully before attempting a question.
#23. What is this component?
#24. This diagram shows the direction of a magnetic field caused by a current flowing through a conductor. Where is the magnetic field strongest?
#25. If a current travelling along a wire changes direction, does the magnetic field also change direction?
#26. Is momentum a vector or a scalar?
#27. Calculate the acceleration of an object which has the following characteristics. Use the following equation v² − u² = 2 a x. Final velocity = 50m/s, Initial velocity 0m/s, Distance travelled = 350m
Rearrange the equation to the following and then substitute in the correct values:
a = v² – u²
2 x
Where:
a = acceleration
v² = final velocity squared
u² = initial velocity squared
x = distance
#28. A car makes a journey to the shop and back. Calculate the overall displacement travelled by the car.
#29. What is this component?
#30. Are voltmeters connected in parallel or series?
#31. When a substance changes from a solid to a liquid, what happens to the mass?
Stays the same because there has been no change in the number of particles. We say that the mass has been conserved.
#32. What the the least dense state of matter?
#33. What is the name of the phase change from gas to solid?
#34. A bar magnet is a permanent magnet – what does that mean?
#35. Is acceleration a vector or a scalar?
#36. Calculate the change in height of the tennis ball in the following scenario. A ball weighs 0.15kg – the change in GPE is 100 J – the gravitational field strength is 10N/kg. Answer to 1dp and include units. ? If you do not know the GPE equation, it is listed below the quiz
#37. With electromagnetism the direction of the current depends on which of the following?
#38. An object with a mass of 5kg is raised to 100m above the ground and has 500 J of gravitational potential energy. What will happen to the gravitational potential energy if the mass was increased to 16.3kg? Calculate the change in GPE where the gravitational field strength is 1 N/kg. Include units. ? If you do not know the GPE equation, it is listed below the quiz
#39. Is speed a vector or a scalar?
#40. What is the boiling temperature of water?
#41. Vectors have which of the following quantities?
#42. What is this component?
#43. What devices are used to determine the shape of a magnetic field?

#47. Which of the following is the correct equation for work done?
#48. What do we call energy that is stored in hot objects?
#49. Which of the following is the equation for acceleration?
#50. A student sets up a parallel circuit with two lamps, two switches and a power source. Each lamp is on a separate route, with a switch placed before it. If one switch is turned off, will the lamp on the other route remain on?
#51. Conventional current goes from:
#52. A coil of wire with current flowing through it is an electromagnet. What else do we call a coil of wire?
#53. Which of the following devices do we use to measure weight? ? 2 answers
Select all that apply:
#54. Nickel is a magnetic material – true or false?
#55. What is the function of an ammeter?
#56. Which of the following describes the Plum Pudding Model of atomic structure?
#57. What is Newton’s Second Law of Motion?
#58. Why are metals good conductors?
#59. Why is the total energy transferred to a kettle’s heating element, more than the total energy of the boiled water inside the kettle?
If you could accurately measure the movement of energy, you would always find that all of the energy is transferred. Energy cannot be created or destroyed, this is known as the Law of Conservation of Energy.
