gradually decrease If a constant force is acting on a particle, the force will tend to accelerate the particle and increase its speed. But, due to increase in speed, the mass of the particle will increase by the relation m = m_o/$\sqrt$(1 - v^2/c^2) leading to decrease in acceleration as constant force is acting. Therefore, after sometime its acceleration will start decreasing gradually.
