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)
What is the opposite word for accelaration?
decelration
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 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.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
Is deceleration and retardation same?
"Deceleration" is a decrease in speed, however you are still going in the SAME direction so it is POSITIVE. "Retardation" is going in the OPPOSITE direction, therefore it is NEGATIVE.
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.
Accelaration is a change in what?
it changes the speed
Are dimple a sign of retardation?
No a dimple is not a sign of retardation.
Does speed increase when the net force is opposite to the direction of motion?
When the net force on a body is in the opposite direction to the motion of the body the speed of the body will never increase rather retardation will take place and the body will lose its speed.
How to calculate retardation?
Retardation = change in vel / time taken
