and if you want more details.. Just go through with 9th class physics (refresher). it will definitely help you.

2Thank You

Ďãřşháñăã Yadav???✊ 7 years, 6 months ago

Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative. Retardation is the rate of decrease in velocity.
