Kids are fascinated with the way things work. This wooden model that has been handcrafted from durable hardwood with smooth-moving parts allows children to explore the concepts of force, speed, motion, direction, and energy.
When a cord is run over a pulley, the direction of the applied force is changed. This is a very useful principle in many different machines, and a basic principle that shows up again and again in physics classes. This device lets students explore and understand this basic principle.
