Question

What is retardation?Is retardation and negative acceleration same?

Answer 1

Answer:-

• Retardation is the rate of change of velocity in which the final velocity remains lesser than the initial velocity.
• Yes, retardation and negative Acceleration are same.

More:-

a = (v-u)/t

where,

• a = Acceleration,
• v = Final velocity,
• u = Initial velocity &
• t = Time taken.

Formula for finding acceleration and retardation is same.

Answer 2

Retardation :

If the velocity of a body increases,the acceleration is positive, and if the velocity of a body decreases, the acceleration is negative.

Yes,retardation and negative acceleration are same.

Retardation is actually acceleration with the negative sign.

More details :-

Acceleration takes place when the velocity of a body changes. The velocity of a body may increase or decrease, according the acceleration is of two types - Positive acceleration and negative acceleration.
