define deceleration?

Answer 1

Acceleration is defined as the rate of change of your velocity with respect to time
Deceleration could be defined as negative acceleration

It is the opposite, it causes your velocity to decrease

Answer 2

Define Deceleration

Answer 3

de·cel·er·ate (d-sl-rt)
v. de·cel·er·at·ed, de·cel·er·at·ing, de·cel·er·ates
v.tr.
1. To decrease the velocity of.
2. To slow down the rate of advancement of: measures intended to decelerate the arms buildup.
v.intr.
To decrease in velocity

something tells me you need this answer in my own words. okay, I'll try. velocity is the rate at which the distance between to points is closed.

I would express that as Velocity=Distance/Time

if at a certain velocity (5mph) the distance (5 miles) is closed in one hour, then deceleration is a decrease in velocity causing a longer time differential. (4mph=5 miles/xTime(1hr 15 minutes))

oops, just looked up acceleration and noticed that time is squared. I don't know why. I was an art major with a minor in Bible.

Plus, if a change in direction is ACceleration. What would be the opposite of a change in direction that could be defined as DEceleration?

Answer 4

Deceleration is the rate of decrease of velocity.

Answer 5

Deceleration is acceleration which results in a decrease in speed in the implied frame of reference.

Answer 6

Negative acceleration is called deceleration. It is also called retardation.

Answer 7

A slowing down of speed, represented by a negative accelleration, such as -2m/s^2

Answer 8

the act of reducing or decreasing of the velocity

Answer 9

it is the opposit of acceleration, it means to move more slowly

Answer 10

rate of decrease in velocity...
