POCT in the ED â¢ Faster does not always lead to better outcome â¢ Lab tests are rarely the rate limiting factor in ED disposition â¢ Process analysis is the key understanding and improving patient throughput in the ED â¢ Test menu selection is a critical component of the potential application of POCT â¢ Match available tests to disposition decisions
Gravity decreases with altitude as one rises above the Earth's surface because greater altitude means greater distance from the Earth's centre. All other things being equal, an increase in altitude from sea level to 9,000 metres (30,000 ft) causes a weight decrease of about 0.29%.
The acceleration due to gravity is taken as a constant (9.81 m/s2). This constant is acceptable at the earths surface, but the actual acceleration is a function of the distance from the center of the earth. Gravitational pull implies force which is a function of acceleration and mass (F=ma). So, no gravitational pull is not the same on all objects.
