The top point on unbalanced force. The top point on the gyroscope is acted on by the force the gyroscope is acted on by the force applied to the axle and begins to move applied to the axle and begins to move toward the left. It continues trying to toward the left. It continues trying to move leftward because of Newton's move leftward because of Newton's first law of motion, but the gyro's first law of motion, but the gyro's spinning rotates it.spinning rotates it.
