Bashir and Keiko are standing in an elevator that is moving upwards. If the elevator suddenly stops, what happens to Bashir and Keiko and why? Provide a very brief response.
When the elevator abruptly stops, both Bashir and Keiko will feel a jolt downwards. Their bodies want to maintain their upward velocity due to inertia, but the floor of the elevator that was pushing them upwards is no longer moving. As a result, they momentarily continue to move upwards as the elevator comes to a halt beneath them. This creates a sensation of being pushed down relative to the suddenly stationary elevator before they come to rest on the floor. The pressure that they feel on their feet from the floor of the elevator would briefly decrease as they slow down and match the elevator's new, stationary position.
