This instrument for measuring spatial linear acceleration sounds very tall. In fact, the principle is that the weight of astronauts can be measured with a spring. Isn't it amazing? Before introducing this space linear accelerometer, let's talk about Newton's second law, which has a wonderful relationship with this accelerometer.
Newton's second law is the relationship between force and acceleration and mass. When acceleration occurs, there must be a relationship between force and mass. According to Newton's second law, F stands for the force in the direction of acceleration, A stands for acceleration, and M stands for the mass of our human body. We can see this relationship according to the formula F=ma. The principle of the space linear acceleration measuring instrument is that a spring in the device exerts a known force on the astronaut holding the bracket, and then the acceleration generated by this force is accurately calculated by the space linear acceleration measuring instrument, so that the mass of our astronaut can be obtained by the formula m=F/a through two known accelerations and forces. This measurement method is often used in the space capsule to monitor the weight of our astronauts at all times to see if their bodies meet the standards during the flight.
Isn't it amazing? There are many places around us where physics is applied, so we should constantly update our knowledge in social and scientific fields through our own continuous learning, so that our wisdom can be applied to our lives. After we know how to measure the weight of astronauts, we should also keep our mouths shut, spread our legs, exercise moderately every day, enjoy a healthy life and keep working hard.
