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. 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
#2. What is Newton’s Third Law of Motion?
#3. What does F represent in the equation for work done?
#4. What state of matter has particles which are far apart and move around independently?
#5. What is this component?
#6. With electromagnetism the direction of the current depends on which of the following?
#7. The needles of plotting compasses are tiny magnets – they always point near the Earth’s North Pole – why is this?
#8. What is the function of an LED?
#9. Jack moves a cube weighing 250N. He moves the cube by 2.5m in a straight line. Calculate the work done by Jack. Answers to 1d.p, include the units. ? Do not include your workings in your answer
#10. 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.
#11. Magnets have north and south poles – if two north poles are put close together what will happen?
#12. Does the total amount of current change from the positive to the negative terminal?
Because current is conserved.
#13. What is the function of an ammeter?
#14. What is this component?
#15. What is the boiling temperature of water?
#16. Which scientist proposed the Plum Pudding Model?
#17. The gravitational field strength is higher on Earth than on the Moon. How does an astronaut’s weight change when they go from the Earth to the Moon?
#18. True or False – Magnetic field lines that are far apart represent the strongest part of the field?
#19. 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?
#20. Is this a parallel or series circuit?
#21. 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.
#22. Calculate the overall distance travelled by the object in the graph.
#23. What is this component?
#24. 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
#25. Which of the following devices do we use to measure weight? ? 2 answers
Select all that apply:
#26. What is this component?
#27. The diagram shows a solenoid. Why is the magnetic field stronger along the centre of the coil than on the outside? ? Select two answers
Select all that apply:
#28. A bar magnet is a permanent magnet – what does that mean?
#29. What do we call energy that is stored in twisted or stretched materials?
#30. What is the name of the phase change from solid to liquid?
#31. A crane raises a concrete bucket 12m into the air. The bucket including the cement weighs 850N. Calculate the work done. Answer to 1d.p and include the units. ? Do not include your workings in your answer
#32. Nickel is a magnetic material – true or false?
#33. The force on a conductor carrying current at right angles to a magnetic field is expressed by which of the following equations?
#34. What is the approximate radius of a nucleus?
#35. Magnets have north and south poles – if two south poles are put close together what will happen?
#36. What is this component?
#37. Complete the sentence. Power is the rate at which…..
#38. What is this component?
#39. Which greek letter represents density?
#40. What state of matter has particles which are close together and vibrate around fixed positions?
#41. What is happening to the speed of the object in the graph between 0 and 8 seconds?
#42. What is a resultant force?
#43. Copper is a magnetic material – true or false?
#44. In a parallel circuit, is the potential difference across each branch –
#45. Complete the equation for power. Power (W) = work done (J) / ……..
#46. Which of the following is the correct equation for work done?
#47. What do we call energy that is stored inside atoms?
#48. 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.
#49. What is the function of a cell?
#50. Electrons are negatively charged, so they move to which terminal of a battery or cell?
#51. Does a circuit need to be closed for current to flow?
#52. Iron is a magnetic material – true or false?
#53. Fill in the blank: A current flowing through a wire causes a ………. field.
#54. Is velocity a vector or a scalar?
