Sid is sending his toy panda Ignatz on yet another adventure! He places him on top of a skateboard and rolls him across the patio. The skateboard comes to an abrupt stop when it bumps into a wooden bench, but Ignatz keeps moving forward and flies into the air! Sid is curious why Ignatz didn't stop moving too, so he and his friends investigate and discover that things in motion stay in motion until they are stopped-and that's inertia!
