When an elevator is moving downward, its acceleration changes to be negative, meaning it is slowing down.
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
The acceleration of a body moving downward on an inclined plane with angle θ when friction is present can be expressed as: a = g(sinθ - μcosθ) where: a = acceleration of the body g = acceleration due to gravity θ = angle of the inclined plane μ = coefficient of friction
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
The rate of change of velocity of a moving object is known as acceleration. Acceleration can be calculated by dividing the change in velocity by the time taken for the change to occur. Positive acceleration represents an increase in velocity, while negative acceleration (or deceleration) represents a decrease in velocity.

Acceleration
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
A force or acceleration
No, because acceleration is the rate of change of velocity.
The direction of acceleration in a moving car is in the direction of the change in velocity, either speeding up or slowing down.
acceleration in a direction that is not parallel to the direction you are moving
