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!

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
