As one of the most practical inventions of the 19th century, the elevator certainly plays an integral role in how modern society functions. In fact, it is safe to say that we would be lost without their presence. With this said, many people are still reluctant to use them due the strange feeling that they get afterwards, which can only be describes as a ‘dizziness’. Here at Elevators Ltd, we have decided to explain why some people are sensitive the movement of an elevator cab…
The planet we live on has a strong gravitational force that allows us to do things like drop a pen or walk along the floor. In fact, thanks to gravity we are never not touching something! This force actually likes to pull everything towards it in order to resist an upwards motion however elevators are designed to transport people up and down, which is precisely the opposite of what gravity would prefer!
The discovery of gravity is the result of mathematician, astronomer and physics Issac Newton who’s bump on the head from an apple is the focus in many high school science classrooms. Following this phenomenon, Newton came up with three laws of motion and the first one states that ‘an object either remains at rest or continues to move at a constant velocity unless acted upon by an external force’. In simple terms, this means that someone at rest (standing still) will continue to remain at rest unless they are forced to move by someone pushing or pulling them along. Amazingly, we can apply this, and gravity, to elevators in order to explain the dizziness that many people get.
We enter an elevator cab when it is stationary, and this means that all of the forces that are acting on our body are at an equilibrium. According to physics, we will continue to remain in a state of rest as long as we are stationary, however when you throw the sudden movement of an elevator working against the force of gravity into the mix, this equilibrium is broken, resulting in a dizzy sensation. Thankfully, it only lasts for a few seconds and thanks to the first law of motion again, quickly disappears after the elevator has stopped moving. After all, once the cab comes to a halt and we leave, the forces acting on our body rebalance themselves.
Interestingly, elevators operate in regards to complicated physics, especially when you bring hydraulic power into the equation. With this said, the team here at Elevators Ltd want to clarify that elevators are still an incredibly safe piece of machinery despite the strange feeling that many passengers feel briefly after a journey. After all, it is simply the result of science in action! To find out more about the weird and wonderful world of elevators, get in contact with the best lift company around today!
