1

Review the idea

Each lab links to the lesson explaining its foundations.

2

Compare with a guide

Follow three experiments. Change one quantity at a time.

3

Explore and explain

Choose other values and answer the questions at the end.

6 labs available

Mathematics

From a rule to the shape of a graph.

Physics

From motion to the quantities that explain it.

Discover how speed, radius and acceleration are connected.

02 · After velocity and acceleration

Circular motion

Distinguish constant speed from constant direction and compare the acceleration needed to turn.
