An acceleration of just 16 g's for an extended time period can be deadly also. The gravity g at depth d is given by g g(1 d/R) where g is acceleration due to gravity on the surface of the Earth, d is depth and R is the radius of the Earth. ds distance moved (m, ft) Acceleration of some known cars. If you know the distance moved and the time used - the acceleration can be calculated as.

It seems that the duration of the acceleration is quite important. Download and Print Car Acceleration Chart. However, it also says that some people may have survived accelerations up to 100 g's. Wikipedia's g-force tolerance page lists 50 g's as "likely death". Then what kind of accelerations can a human body withstand? In a previous episode of Mythbusters - the jumping from a building with bubble wrap one, they state that stunt men aim for a maximum acceleration of 10 g's. As explained earlier, the SI unit of force is the newton. But wouldn't that be cool? If there was some force field that could stop you (or shoot you off like a bullet) without causing damage? Yes. The equation Fnetma F net m a is used to define net force in terms of mass, length, and time. The only force that pulls on all parts of a body would be the gravitational force (since all the parts have mass). No inner spring compression means no body damage. What if there was some long range force to accelerate this two-ball model of a body? If this same force was on both balls in the model, you could get a super high acceleration without having to compress the inner spring. So, large accelerations can cause damage. Both Height and StopDist must be in the same units of measurement, so if using a Height of Meters and a StopDist of Centimeters. This is where the damage comes into play. If this spring is compressed too much, it could break. The greater the acceleration, the greater this spring force must be and the more compressed the inner spring will be. This means that the force the inner spring exerts on the top ball must be greater than the gravitational force. Since it has to accelerate up, it must have a net force pointing upwards. You get this value from the Law of Universal Gravitation. If the body falls and collides with the ground, it must accelerate in the upward direction. The 9.8 m/s2 is the acceleration of an object due to gravity at sea level on earth. In this model, there are two balls connected by a spring.
