Oh, dude, so like, when something is slowing down, it's actually experiencing negative acceleration. It's like the opposite of when you speed up, you know? So, they call it retardation because it's like saying, "Hey, slow down, negative acceleration coming through!" It's just a fancy way of saying things are getting slower, man.

Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
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 positive negative and zero acceleration is?
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
How can you have negative acceleration but not negative speed?
The negative part in negative acceleration is indicating direction, as acceleration is a vector quantity. Speed however, is a scalar and has magnitude only and therefore cannot be negative. An example could be -2.6ms-2 meaning that there is an acceleration of 2.6ms-2 but in the opposite direction to other vectors.
