1.	Can you measure the acceleration of a train, if the train is moving at a constant velocity and the sensor is located on the train?(a) Yes(b) NoThis question was addressed to me in exam.My doubt is from ADXL335 Accelerometer Sensor in chapter Interfacing of Sensors, Actuators, and Other Modules of Arduino
Answer» RIGHT answer is (a) Yes Best explanation: Yes, you can measure the ACCELERATION of the train but in this CASE the acceleration VALUE of the train is going to be 0 SINCE acceleration is the rate of change of velocity with time and in this case since the velocity of the train is constant with respect to time, then the acceleration measured by the sensor should be 0.
