Retardation is defined as the rate of decrease of velocity with time. suppose if a car is slowing down,its velocity is decreasing,so its acceleration is negetive. But retardation is positive. Retardation is negetive of acceleration.

What is retardation example?
Retardation can also be named as negative acceleration or deceleration. Example: When we apply brakes to the vehicle, the velocity of the vehicle decreases (Final velocity becomes less than initial velocity). This means that retardation has taken place.
What is the symbol of retardation?
Answer: The SI unit of retardation is metre per second squared (m/s2).
What is retardation and SI unit?
The SI unit of Retardation (m/s²) meter per second squared. According to the definition, Acceleration can be defined as the rate of the change of the velocity of any object. Retardation is the total opposite of acceleration i.e., negative acceleration.
What is retardation and its formula?
a=tv−u. Here, u is the initial velocity, v is the final velocity and t is the time. If the initial velocity is greater than the final velocity then the above expression becomes the retardation. Therefore, the expression for the retardation is a=tv−u.
What is retardation also called?
Medicine and biology. Mental retardation, also known as intellectual disability, a disorder characterized by significantly impaired cognitive functioning and deficits in adaptive behaviors.
What is difference between acceleration and retardation?
Retardation is the inverse of acceleration and is defined as a decrease in velocity per unit of time. Acceleration can be positive (+), zero (0), or negative (-). Retardation is the inverse of acceleration. Negative acceleration is also referred to as retardation or deceleration.
What is retardation in CBSE 9th physics?
Answer: Retardation is nothing but a negative acceleration. The body’s velocity will either increase or decrease. The velocity shift is known as acceleration.
Is retardation always positive?
It can be positive, Negative or Zero. It can be positive, Negative or Zero. Rate of Negative change of velocity with respect to time is called Retardation.
What is the CGS unit of retardation?
SI unit of retardation is m/s2 and its CGS unit is cm/s2.
What is the retardation effect?
Retardation effects are due to the electromagnetic field needing to travel for a long time to reach the neighboring atom when the separation distance is long. From: Fluidized Bed Technologies for Near-Zero Emission Combustion and Gasification, 2013.
What is retardation answer in one word?
Solution. Retardation is the decrease in velocity per second.
What is meant by retardation or deceleration?
Retardation (or deceleration) of a body whose velocity is decreasing with time is defined as the negative of acceleration. In other words, it is equal to the magnitude of acceleration of a body whose velocity is decreasing with time.
What is the dimension of retardation?
a= u – v/t it is formula of retardation.
Why is retardation negative acceleration?
The acceleration that acts in a direction opposite to the direction of velocity is termed as retardation, which is why it is considered ‘negative acceleration’. As a result of retardation, the velocity of a body decreases.
How do you find acceleration and retardation?
Retardation is negative acceleration. By definition of acceleration, we know v = u + at. Therefore we can find retardation. Also, we can find the distance covered by the car from the formula $s = ut + dfrac12at^2$.
Is negative acceleration same as retardation?
If the velocity of the object decreases then the object is said to have a negative acceleration and the meaning of retardation is decreased. Therefore, retardation means negative acceleration.
Is retardation a vector or scalar?
Retardation, or negative acceleration, is nothing but an acceleration which decreases the speed. Its SI unit is same as that of acceleration. Just like acceleration, it has both magnitude and direction, i.e. it is a vector quantity.
What are 3 types of acceleration?
Answer: The three types of acceleration are 1) Change in velocity 2) Change in direction 3) Both change in velocity and direction .
Is acceleration is also called retardation?
In simpler terms, retardation means negative acceleration. The term “acceleration” means a change in velocity. Generally, acceleration refers to an increase in velocity, but when it denotes a decrease in velocity, it is called retardation.
What is the S.I. unit of acceleration?
The SI unit of acceleration is metres/second2 (m/s2).
What is uniform retardation?
An object is said to be moving with uniform deceleration if it decrease its velocity by equal amount in equal intervals of time. It is also known as uniform retardation.
What is the direction of retardation?
Retardation is negative acceleration i.e acceleration in the direction opposite to motion.
What is scalar or vector?
A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.
Is force a vector or scalar?
Force is not a scalar quantity. Force is a vector quantity, as it has both direction and magnitude.
