Question

Define accelaration and deaccelaration​

Answer 1

Acceleration :

Acceleration is the act of increasing speed. ... Acceleration comes from the Latin word accelerationem, which means "a hastening." When you hasten, you hurry, so acceleration is a speeding-up. Maybe you are walking to an appointment and realize you will be late. You pick up your pace — that's acceleration.

deaccelaration :

Deceleration is a slowing down: the unexpected deceleration of your car might mean that you've run out of gas. Use the noun deceleration when you talk about a gradual decrease in speed.

Answer 2

Answer:

Acceleration can be caused by either a change in the magnitude or the direction of the velocity.

Deacceleration is an acceleration with a direction opposite to that of the velocity.
