Rate of change of position (displacement) is known as:
|
|
acceleration
|
|
|
velocity
|
|
|
Force
|
|
|
speed
|
Explanation:
Detailed explanation-1: -The rate of change in displacement is referred to as velocity. In general, the velocity of an object changes during its motion. It is also called the first-order derivative of displacement with respect to time. It can be expressed as v = d x d t .
Detailed explanation-2: -The rate of change of velocity is called acceleration.
Detailed explanation-3: -The rate of change of position is velocity, and the rate of change of velocity is acceleration. Speed is the absolute value, or magnitude, of velocity. The population growth rate and the present population can be used to predict the size of a future population.
