Variants of the formula above are used when solving for initial velocity, final velocity or time. Equations for initial velocity, final velocity, and time Remember to always have the time unit of the speed measure being the same as the duration measure. If it was in meters and seconds, it would be in m/s 2 (meters per second squared). The resulting unit will depend on the units for both time and distance, so if your input was in miles and hours, the acceleration will be in miles/h 2. Where a is the acceleration, v 0 is the starting velocity, v 1 is the final velocity, and t is the time (acceleration duration or t 1 - t 0). The formula for acceleration expressed in terms of the initial velocity (speed), final velocity and the acceleration duration (time) is: Negative g-force is much harder to handle, with the limit being between -2g and -3g. A typical person can handle 5g for a short duration without passing out, while trained pilots with suits and other equipment can withstand 9g for prolonged periods of time. However, the human body deals much worse with vertical g-forces that are aligned with the spine. If perpendicular, many humans can endure 20g for about 10 seconds, 10g for a minute, and 6g for up to 10 minutes, without any ill effects. The human body can handle a different amount of g-force depending on whether it is perpendicular to or along the spine. The value of ɡ n is a nominal midrange value on Earth, originally based on the acceleration of a body in free fall at sea level at a geodetic latitude of 45°, the actual acceleration of free fall on Earth varies according to location. G n is equal to 9.80665 m/s 2 and is the standard acceleration due to Earth's gravity according to the International Service of Weights and Measures. It can be used to estimate the deceleration required to come to a full stop in a given number of seconds, for example, or the breaking path of a vehicle decelerating at a given rate.
The calculator can be used to calculate deceleration as well, simply by entering a lower value for the final speed. km/h 2), meters per second squared (m/s 2) and standard gravity units ( g n, often just g). The output is always in the input unit squared (e.g. You need to know 3 of the 4: acceleration, initial speed, final speed and time (acceleration duration) to calculate the fourth. due to the many different units supported. This acceleration calculator is useful for any kind of vehicle or object: car, bus, train, bike, motorcycle, plane, ship, space craft, projectile, etc.
