Calculate the time taken for a certain distance to be travelled given the average speed and the distance travelled.

Small, simple question.

A measurement is performed multiple times for the same object, the student will

• calculate the mean result
• calculate the standard error on the mean 
• write the mean±error to the correct precision as defined by the error written to 1 significant figure 

Advice is provided including on performing the calculations in Python or spreedsheets together with further reading.

This question demonstrates how to use GeoGebra applets in explore mode.

The student must construct a polygon by adding points one at a time. At any point, they can answer the question, "Is the centroid inside the polygon?"

GeoGebra's IsInRegion command is used to decide if the centroid is inside the polygon.

Questions that gives either an am or pm time displayed on a 12-hour clock and asks for its equivalent time in 24-hour mode. The question uses JSXGraph to generate the displayed 12-hour time. Times are randomly generated in 5 minute increments.

Calculate distance given speed and time.

Given speed and time, calculate distance.

Given speed and distance, find time. convert time units.

Is this number divisible by 2? Half the time the number is, half the time it isn't. Steps give the divisibility test.

Students are shown a graph of the value of a machine over time. The line equation is randomised.

They are asked to evaluate value at a given time, and the time at which a given value is reached. They are asked when the machine has no value, and the range of times over which the model is valid. They are also asked to explain the physical meaning of the gradient.
