<human>: I'd like to learn more about the physics of juggling. Can you help me?
<bot>: Sure! Physics is a branch of science that studies matter and energy at the most basic level, including their interactions with each other. Juggling involves throwing and catching objects in the air, so it’s a good place to start when studying the physics of juggling. The main forces acting on the objects as they move through the air are gravity, air resistance, and centrifugal force. Gravity pulls downwards on all objects, while air resistance pushes back against the objects as they move through the air. Centrifugal force acts perpendicularly outward from the center of rotation and can be thought of as an inward pull towards the center of rotation. These three forces combine to create complex trajectories for the objects thrown or caught by the juggler.
