#1. What is this component?

#2. Are ammeters connected in series or in parallel?

#3. What do we call energy that is stored in twisted or stretched materials?

#4. What is this component?

#5. What is the force acting on a conductor carrying current at right angles to a magnetic field when: magnetic flux density = 0.005 T , current = 3 A and length of wire = 150m?

#6. What is this component?

#7. 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:

#8. What the the most dense state of matter?

#9. What is the equation for kinetic energy?

#10. Magnets can attract magnetic materials – true or false?

#11. Does a circuit need to be closed for current to flow?

#12. In 1897 JJ. Thomson did a series of experiments that led to the discovery of which particles?

#13. 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?

#14. What is this component?

#15. With electromagnetism the direction of the current depends on which of the following?

#16. What is this Sankey Diagram showing?

#17. Are gases fluids?

#18. Is acceleration a vector or a scalar?

#19. True or False – Vector quantities only have magnitude?

#20. What is this component?

#21. Does the total amount of current change from the positive to the negative terminal?

Because current is conserved.

#22. Which of the following was the Rutherford Model of atomic structure?

#23. What does F represent in the equation for work done?

#24. If a car is moving but the forces are balanced – what will happen to the speed of the car?

#25. If a current travelling along a wire changes direction, does the magnetic field also change direction?

#26. What devices are used to determine the shape of a magnetic field?

#27. What is current measured in?

#28. What do we call the energy transferred by a force?

#29. What is Newton’s Third Law of Motion?

#30. What is the function of a cell?

#31. 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.

#32. A car makes a journey to the shop and back. Calculate the overall displacement travelled by the car.

#33. What is a battery?

#34. Which of the following statements is correct?

#35. What is this component?

#36. Is weight a vector or a scalar?

#37. An object with a mass of 5kg is 100m above the ground and has 35 J of gravitational potential energy. What will happen to the gravitational potential energy if the mass was increased to 10kg?

#38. Which theory do we use to describe states of matter?

#39. What is induced magnetism?

#40. What is the approximate radius of a nucleus?

#41. Is this statement true or false? As potential difference increases, the current across a component increases?

#42. What the the least dense state of matter?

#43. 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.

#44. 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.

#45. True or False – Magnetic field lines are used to show how a single north pole would move from north to south?

#46. What is this component?

#47. What do we call energy that is stored inside atoms?

#48. A wire carrying a current experiences a force near a magnetic field. The size of the force is dependant on which three quantities?

Select all that apply:

#49. How is kinetic energy stored?

#50. Complete the sentence. Power is the rate at which…..

#51. What is Newton’s Second Law of Motion?

#52. What is this component?

#53. Which of the following best describes energy?

#54. Why did Ernest Rutherford’s experiments with gold foil demonstrate that most of atoms consists of empty space?

#55. Is mass a vector or a scalar?

#56. Copper is a magnetic material – true or false?

#57. What is the boiling temperature of water?

#58. Which of the following is the correct equation for density?

#59. Magnesium is a magnetic material – true or false?

#60. What is happening to the speed of the object in the graph between 0 and 8 seconds?
