Difference between the linear velocity returned by physics.data.sensordata and physics.data.object_velocity

What's the difference between the linear velocities in physics.data.sensordata and physics.data.object_velocity? They seem to be different. Thank you for the help.

Start by reading the physics.data.sensordata and physics.data.object_velocity entry points and their surrounding API documentation. Determine how each linear velocity is defined and reported, then document the distinction with enough context for users to know which value to use.
