This phenomenon can be explained by the concept of inertia. Inertia is the tendency of an object to resist changes in its velocity or motion.
When the skateboarder hits the rock, the rock imparts a force on the skateboard in the opposite direction of the skateboard's motion. This force causes the skateboard to come to a stop or slow down. However, since the skateboarder's body is not directly connected to the skateboard, their body is not subject to the same force.
Due to inertia, the skateboarder's body tends to maintain its state of motion even though the skateboard has stopped. This means that their body continues to move forward with the same velocity it had before hitting the rock.
It is worth noting that the skateboarder's body will eventually be affected by external forces such as friction with the ground or air resistance, which will gradually slow down their motion. However, in the immediate aftermath of hitting the rock, their body will continue to move forward.
Forces that Change Motion.
A skateboarder hits a small rock which stops their skateboard, but their body continues to move forward. Explain why this is the case.
