It is not at rest.
speed it up slow it down and change direction. Forces can: - Cause and acceleration o Speeding up o Slowing down o Change direction - Do nothing - Cause work (w = Fd) - Ie. Change shape

Deceleration or negative acceleration
The falling motion of the broom is the acceleration of the broom The broom hitting the floor and slowing down is the deceleration of the broom. Remember, acceleration is the speeding up and deceleration is the slowing down (De is the Latin root meaning down, so down in speed/ decreasing in speed...)
Whenever any object moves through air (eg an aeroplane) it observes four forces 1 Drag force 2. lift force 3.weight of object 4.thrust created by the propellers or engine of the object. The drag force is directed opposite to the direction of moment of the object and slows the object down.
This would indicate negative acceleration, which would mean that the object in question is speeding up.
It slow down, and eventually reverse direction.
It is called deceleration.
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
This is a moving object that is slowing down.
An object that is accelerating may be slowing down, gaining speed, and changing direction.
yes the acceleration can take a negative value. for example an object with an accleration of -2 ms-2 would be slowing down. However this is normally called deceleration.
When a moving object is slowing down, i.e. its speed is decreasing.
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
Negative acceleration, also known as deceleration.
