A clothes amount sensing method in a washing machine which is capable of reducing clothes amount sensing errors caused by frictional forces, thereby achieving an enhancement in accuracy and reliability. The method includes an acceleration step for accelerating, to a predetermined RPM, a motor adapted to rotate the wash tub, a constant-speed step for maintaining the motor at the predetermined RPM when an RPM of the motor reaches the predetermined RPM in accordance with the acceleration step, a deceleration step for turning off the motor to decelerate the motor, following the constant-speed step, and a clothes amount determination step for determining the amount of the clothes by use of equations of motion respectively established in the acceleration, constant-speed, and deceleration steps.
