An accelerometer measures proper acceleration, which is the acceleration it experiences relative to freefall.This is most commonly called G-Force (G) For example, an accelerometer at resting on a table would measure 1G ( 9.81 m/s2) straight upwards 3 Gyroscopes. pendulous lower element of the gyro, and this force is precessed through 90° to indicate a bank to the right. These acceleration errors restrict the use of air driven horizons to. A powerful motorcycle can accelerate from 0 to 30.0 m/s (about 108 km/h) in 4.20 s. What is the angular acceleration of its 0.320-m-radius wheels? (SeeFigure 10.6.) Figure 10.6The linear acceleration of a motorcycle is accompanied by an angular acceleration of its wheels. Strategy We are given information about the linear velocities of the. 1 Real World 2 Work in Progress 3 Mass and Inertia 4 Velocity 4.1 Units 4.2 Direction 4.3 Combining multiple vectors 5 Acceleration 5.1 Units 5.2 Direction 6 Force 7 Torque 8 Relativity The physics discussed in this section reflect the real world. If you are looking for game mechanics, see the game mechanics category. The thruster mechanics and Gyroscope mechanics mechanics discuss the areas. acceleration¶ The x, y, z acceleration values returned in a 3-tuple and are in \(m / s ^ 2.\) gyro¶ The x, y, z angular velocity values returned in a 3-tuple and are in \(degrees / second\) accelerometer_range¶ Adjusts the range of values that the sensor can measure, from +/- 4G to +/-30G Note that larger ranges will be less accurate Gyroscopic Precession : Precession of a gyroscope under the torque due to gravity. Let L be the angular momentum, be the torque, M be the mass of the gyroscope, g the gravitational acceleration, and r the torque arm. Then (1) so (2) But the torque is given by (3) Using (4) where dL is perpendicular to L because of the torque, it follows that (5.
