What's wrong with my code?

Hello everyone, I was just wondering why this piece of code is not working. The code get uploaded normally to arduino But when I move the gyroscope it just give me random values of X & Y & Z Im expecting 0,0, variable... I checked the connection and it was correct I thought either the sensor is broken or the code is wrong, I'm using it to measure the acceleration of a moving object Any ideas??

#include "MPU9250.h"

MPU9250 mpu;

void setup() {
    Serial.begin(115200);
    Wire.begin();
    delay(2000);

    if (!mpu.setup(0x68)) {
        while (1) {
            Serial.println("MPU connection failed. Please check your connection with connection_check example.");
            delay(5000);
        }
    }

   
    Serial.println("Accel Gyro calibration will start in 5sec.");
    Serial.println("Please leave the device still on the flat plane.");
    mpu.verbose(true);
    delay(5000);
    mpu.calibrateAccelGyro();

    Serial.println("Mag calibration will start in 5sec.");
    Serial.println("Please Wave device in a figure eight until done.");
    delay(5000);
    mpu.calibrateMag();

    print_calibration();
    mpu.verbose(false);
}

void loop() {
}

void print_calibration() {
    Serial.println("< calibration parameters >");
    Serial.println("accel bias [g]: ");
    Serial.print(mpu.getAccBiasX() * 1000.f / (float)MPU9250::CALIB_ACCEL_SENSITIVITY);
    Serial.print(", ");
    Serial.print(mpu.getAccBiasY() * 1000.f / (float)MPU9250::CALIB_ACCEL_SENSITIVITY);
