# What Is The Meaning Of Uniform Retardation?

## What is the example of uniform retardation?

Example of uniform retardation: If a car moving with a velocity ‘v’ is brought to rest by applying brakes, then such a motion is an example of uniform retardation..

## What is retardation Class 9?

Retardation is nothing but a negative acceleration. The velocity of the body may either increase or decrease. The change in velocity is known as acceleration. If the velocity of the body increases, acceleration is said to be positive. … Retardation is acceleration with a negative sign.

## How do you get uniform retardation?

Answer: So formula will be the same as that of acceleration. Where v = final velocity, u= initial velocity & t= time taken to change the velocities. So in case of v

## Why retardation is called negative acceleration?

Negative acceleration always indicates that the acceleration is in the direction opposite to that of the motion of the body. Hence, negative acceleration (or retardation) always means that the body is slowing down.

## How do you find retardation?

So formula will be the same as that of acceleration. Where v = final velocity, u= initial velocity & t= time taken to change the velocities. So in case of v

## What is retardation example?

Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative. Examples of retardation motion are: 1) Velocity of vehicle decreases when brake is applied.

## Which quantity is retardation?

Retardation, or negative acceleration, having both magnitude and direction, is a vector quantity.

## What do we mean by retardation?

Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.

## What is acceleration for class 9th?

Class 9 Physics Motion. Acceleration. Acceleration. Acceleration: It is a measure of the change in the velocity of an object per unit time. Acceleration can be caused either by change in direction of motion or change in speed or both.

## Is retardation a disability?

Intellectual Disability (ID) (formerly called mental retardation) is the most common developmental disability–nearly 6.5 million people in the United States have some level of ID.

## What causes retardation?

Causes of mental retardation include fetal alcohol syndrome and fetal alcohol effect; brain damage caused by the use of prescription or illegal drugs during pregnancy; brain injury and disease; and genetic disorders, such as Down syndrome and fragile X syndrome.

## What is meant by 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 formula of retardation?

the formul for retardation is same as the formula for accelaration which is v-u/t… but when we say retardation it means we are moving in the opposite direction of motion so in that case the anwser which we will get will be negative. for example if the acceleration is 2m/s2 then the retardation is -2m/s2.

## Is retardation and acceleration the same?

Acceleration of a body is defined as the rate of change of its velocity with time. … Retardation means negative acceleration. If the velocity of a body decreases,the acceleration is negative.

## What is retardation force?

Forces that resist relative motion (like air resistance or friction) are called ‘retarding forces’. … No force can in general ‘resist motion’ make things stop moving because it doesn’t mean anything to say whether something is moving or not, only whether it’s moving relative to something else.

## What is the difference between deceleration and retardation?

Deceleration and retardation are the same thing. They both are terms used to define negative acceleration or slowing down of speed.
