The rate of change of displacement is called a velocity.
I think you mean the "rate of CHANGE" of velocity. (If you don't, then the question is meaningless.) The rate of change of velocity is called " acceleration ".
acceleration
The increase in velocity is called acceleration and an decrease is called deceleration.
acceleration
Rate of change in position is called velocity.
The rate of change of displacement is called a velocity.
Jerk is the term. No, really, it is.
The rate of change of motion is called jerk, jolt, surge, or lurch. The rate of change is derivative of motion with respect to time, velocity, and/or position.
This is called reaction rate.
Rate of change of distance is called speed.Rate is defined as change with respect to time.
The rate of change in velocity is called acceleration.
slope
I think you mean the "rate of CHANGE" of velocity. (If you don't, then the question is meaningless.) The rate of change of velocity is called " acceleration ".
A change in position in a certain amount of time is called motion.
It is called rate of change.
Depending on the context, the rate of change may be called different things. In algebra, we recognize rate of change as slope. Or, more simply, change in y over change in x. In calculus, the rate of change is the slope of the line tangent to the curve. In terms of chemistry, the rate of change would refer to the reaction rate.
