The rate of acceleration is constant.
That depends on the size, shape, and weight of the falling object, and also on its instantaneous falling speed ... that is, the rate of deceleration is not constant.
rate of acceleration
Depending on the situation, a rate of change can be constant (at least over a certain time period), or it may be non-constant.
Drying rate is not constant throughout the drying process. Drying rate generally decreases with the decrease of free moisture content. ( water in food is present in different forms; bound and unbound.Its easy to remove unbound moisture. In a drying curve, there's a constant rate drying period and a falling rate drying period. Depending on the equilibrium moisture content, critical moisture content and the final moisture content there are different formulas for calculating drying rates.
terminal
Terminal Velocity
terminal speed
because the number of protons increase constant across the period
Constant speed.
The speed is called "terminal velocity".
There is no difference between them they are same rate constant is another name of specific rate constant
