The crew on the ship prepare to perform a "flip and burn" manuever. This manuever puts an intense toll on the crew, as they need to strap in and inject themselves with some fluids during it. This clip illustrates that the effects of gravity and acceleration should be indistinguishable.

Sam makes a daredevil move and skateboards down the California Incline. As much as he enjoys the ride, he has trouble stopping his skateboard when he gets near the end of the Incline.

Sheldon explains how he uses a toy train and a ball to prove Newton's first law of motion. As the train moves, he pushes a button to propel the ball in the air. The ball lands in the same spot on the train where it was propelled. The ball moves at a constant velocity in an inertial frame of reference.

The MythBusters conduct a test at NASA to determine whether a flag on the moon would wave as it does in the video footage of the first moon landing. They find that momentum alone can keep a flag moving in a vacuum; wind is not needed.

Homer slicks the floor with oil in an attempt to injure himself at work. Due to the significantly reduced friction, he stays in motion at the same speed and direction, thus failing to harm himself.
