Slow is broad and can describe any low speed. Gradual is about something happening step by step over time, usually change or progress. Gradual does not describe a person’s walking speed.
Slow Vs Steady
Steady means consistent and regular, often not changing speed. Something can be steady without being very slow. Slow only means low speed, not necessarily consistent speed.
