Levers, gears and torque
The same force has different turning effects at different distances from a pivot. Both balances and gears depend on this relationship.
Reference age · UK/US 13+ · East Asia 13+Open modelMass, velocity, force and energy describe different aspects of motion. The experiments let you change the conditions and compare measurements, giving the quantities and laws something concrete to refer to.

A pendulum’s length affects a clock’s timing. Two linked pendulums can also amplify a small difference in their starting positions.

The particles inside atoms are more than a list of names. Matter particles, antiparticles and interaction carriers have different roles. Beta decay and the Higgs field give us concrete examples of the relationships in the particle table.

Pulling quarks apart puts energy into their field. Continuing can produce new particles rather than an isolated quark.
