#12. What is Newton’s First Law of Motion?
#13. Magnets can attract magnetic materials – true or false?
#14. When two magnets are placed alongside each other – what is the best way to describe the shape of the magnetic field they produce?
#15. An electric motor does 70,000 J of work in 200 s. Calculate the Power of this action. Include the units and answer to 1d.p ? Do not include your workings in your answer
#16. Which greek letter represents density?
#17. During Ernest Rutherford’s experiments with gold foil, why did some of the particles bounce back?
#18. The melting point of gallium is 29.8˚C and the boiling point is 2204˚C. What state is gallium at 25˚C?
#19. Calculate the acceleration of the object in the graph between 5 and 6 seconds.
This is a straight-line graph.
Calculate the gradient of a straight-line graph using the following:
y₂ – y₁ / x₂ – x₁
30-20/6-5 = 10m/s²
This is the same as a simpler version:
Rise/run
or vertical distance / horizontal distance
#20. Is weight a vector or a scalar?
#21. What is this Sankey Diagram showing?

#24. What is acceleration?
#25. What is the name of the phase change from liquid to gas?
#26. Does the total amount of current change from the positive to the negative terminal?
Because current is conserved.
