Joints are structures in our body that connect bones and provide cushioning with cartilage and synovial fluid. They allow for smooth movement and prevent bones from scratching or bumping against each other when we move. Additionally, muscles, tendons, and ligaments surrounding the joints provide support and stability during movement.
Joints in the body are lined with a smooth, slippery tissue called cartilage that helps reduce friction between bones. Additionally, a lubricating fluid called synovial fluid within the joint cavity helps to cushion and protect the bones during movement.

By bumping into each other
Calorthic
The transfer of thermal energy by molecules bumping into each other is known as conduction. Thermal energy is energy that comes from heat.
Pebbles bumping against each other in a stream are called "abrasion." This process occurs as the flowing water causes the pebbles to collide and rub against each other, eventually wearing them down over time.
