Class 9 -what is the formulae for finding retardation in physics?
Retardation or deceleration is negative accelaration formula for finding retardation is same as that of accelaration: v-u/t, where v is the final velocity, u is the initial velocity and t is the time taken. eg- a bus is travelling at 20 m/s. Brakes are applied to stop the bus. The total time taken by the bus to stop is 2 s. Find its retardation. ans- v=0; u=20; t=2 accelaration= 0-20/2 a= -10 m's^2 retardation= 10 m/s^2 (because retardation is negative accelaration)
Why is the value of retardation is negative?
Retardation, often referred to as negative acceleration, is considered negative because it indicates a decrease in the velocity of an object over time. In physics, acceleration is defined as the rate of change of velocity, and when an object slows down, its change in velocity is in the opposite direction to its motion. This results in a negative value for retardation on the acceleration scale. Thus, it signifies that the velocity is decreasing rather than increasing.
How to calculate retardation?
Retardation = change in vel / time taken
How do you find retardation?
Retardation is the opposite of acceleration.It starts from a non zero uniform velocity.For this to happen any velocity (not zero) of a vehicle should go on decreasing.The rate of decreasing may be anything.If it is decreasing then that is retardation.
How can you find the retardation of a curve in a speed time graph?
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
What is retardation measured in physics?
In physics, retardation refers to the decrease in velocity or speed of an object over time. It is measured in units of acceleration, typically meters per second squared (m/s^2). Retardation can be caused by forces such as friction, air resistance, or gravity.
How does retardation in physics occur?
In physics, retardation refers to a decrease in the speed of an object. This can occur due to forces like friction, air resistance, or gravity acting in the opposite direction to the object's motion, causing it to slow down. Retardation is the opposite of acceleration, where an object's speed increases.
How do you measure retardation in physics?
Retardation is typically measured in physics as the rate at which an object slows down, quantified by the decrease in velocity over time. This can be calculated using equations of motion and may be influenced by factors such as friction or air resistance. The unit of measurement for retardation is usually in meters per second squared (m/s^2).
What does retardation mean in physics?
Retardation means deceleration or the negativity to speed. It's synonyms Disintegrate, Prejudice, Destruct etc. The formula of retardation is V - U/ T where V is the final position U is the initial motion and T is the time taken by object.

What is pseudo-retardation?
Pseudo-retardation would be something that resembles or looks like retardation, but actually isn't. The term literally means, fake retardation.
Are dimple a sign of retardation?
No a dimple is not a sign of retardation.
How to calculate retardation?
Retardation = change in vel / time taken
Does over-study causes mental retardation?
Overstudy does not cause mental retardation.
What are the release dates for Retardation - 2015?
Retardation - 2015 was released on: USA: 2015
What is constant retardation in physics?
Constant retardation is a type of motion where an object is slowing down at a steady rate. This means that the acceleration in the opposite direction of motion is constant. It can be described by equations such as (v = u + at) and (s = ut + 0.5at^2), where (v) is the final velocity, (u) is the initial velocity, (a) is the constant acceleration, (t) is the time, and (s) is the displacement.
When there is acceleration due to gravity present according to newtons third law even retardation due to gravity should be present is it present or not?
I think you should master basic English before trying Physics.
