It's a common experiment, performed in physics classes throughout the world.
If velocity is km/hr and time is in hours then acceleration will be in km/hr2
Velocity (acceleration x time = velocity).
silicon & oxygen.
i believe roughly 70% (not completely sure though) I'm not really sure, but something like 70% of the earths surface..

because all are measured at the same radius from the earths cog, if you doubled this distance, the acceleration would be only one quarter that of the surface
Force (newtons) = mass (kg) * acceleration (m/s/s) > Acceleration at earths surface radius = 9.82 m/s/s
Acceleration can be measured using an accelerometer.
A Richter scale measures the movement of the earths surface which happens during an earthquake.
Acceleration is measured using an instrument called an ACCELEROMETER The simplest home-made accelerometer is a liquid-surface accelerometer, with water in a transparent liquid container with boxy sides. The slope of the liquid surface is a measurement of acceleration.
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
The acceleration due to gravity decreases with height above the Earth's surface according to the inverse square law. Therefore, at a height of approximately 3186 km above the Earth's surface, the acceleration due to gravity would be half of what it is on the surface. This is known as the point of geosynchronous orbit.
earth is 81.3 times the mass of the moon . acceleration due to gravity at earths surface = 9.82 (m/s)/s acceleration due to gravity at moons surface = 1.62 (m/s)/s . 1 kg at earths surface, force = 1 * 9.82 = 9.82 newtons 1 kg at moons surface, force = 1 * 1.62 = 1.62 newtons
If you have a known rate of acceleration and radius (such as at the earths surface), you can use the following equation to calculate the acceleration at another radius.a = k / ((d / r)^2)key:a = new acceleration rate ((m/s)/s)d = new radius (metres)k = known acceleration rate ((m/s)/s)r = known radius (metres)so if:d = 9 000 000 metresk = 9.82 (m/s)/s (acceleration at earths surface)r = 6 371 000 metres (radius at earths surface)then:a = 4.92 (m/s)/s
Standing at surface radius its = 9.82 (m/s)/sbut double the radius and the acceleration drops to 9.82 / ((2 / 1)2) = 2.455 (m/s)/s
Different air pressure, so there is more/less air resistance.
Seismic waves are the vibrations from earthquakes that travel through the earths surface and is measured bye the shaking you feel.
