what Is meant by retardation and state it's law.
explain velocity
Answers
Answer:
Explanation:
Retardation means negative acceleration. ... So when the velocity of a body increase, the acceleration is said to be positive and when the velocity of a body decrease, the acceleration is said to be negative(Retardation). A body is said to be retarded if its velocity is decreasing.
velocity:Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
Answer:
what Is meant by retardation?
Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays. Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative.
explain velocity
The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated but velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. The SI unit of it is meter per second (ms-1) if there is a change in magnitude or the direction in the velocity of a body the body is said to be accelerating.
law of retardation
Congress passed Rosa's Law, which changed references to “mental retardation” in specified Federal laws to “intellectual disability,” and references to “a mentally retarded individual” to “an individual with an intellectual disability.” Rosa's Law also required the Federal agencies that administer .
