What else can I help you with?
Two words for what happens when an objects velocity decreases?
negative acceleration
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
Which term explains whether an objects velocity has increased or decreaseed over time?
Acceleration describes whether an object's velocity has increased or decreased over time. An object has positive acceleration if its velocity is increasing, negative acceleration if its velocity is decreasing, and zero acceleration if its velocity is constant.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
What happens to acceleration during a crash?
During a crash, the acceleration of the objects involved can increase rapidly due to the sudden change in velocity. This acceleration can lead to significant forces being applied to the objects, which can result in damage or injury.
When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).

When velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
Is it possible for an objects velocity to be perpendicular to the objects acceleration?
no
How can you calculate the velocity and acceleration of falling objects?
Acceleration:Always the same, doesn't need to be calculated. Acceleration of gravity = 9.8 meters (32.2 ft) per second2Acceleration of gravity is negative (points down).Velocity:(Initial velocity) + [ (acceleration) x (time) ]Positive velocity = moving upNegative velocity = moving down

It is physically impossible for an object to have a negative acceleration and yet be speeding up?
Not yet possible, maybe later. Acceleration is the first derivative of the speed by definition. So this comes back to a mathematical question. When do we have a first derivative negative? The only possibility is that the function has a negative slope, meaning in the case of the object trajectory, that the object's speed is decreasing. If you could have objects decelerating while speeding up you should also think about accelerating objects winding down and steady objects wandering abound. As this was not easy to find conceptual representation for such situations, God just said to objects "thou will stop speeding up when you have a negative acceleration, capito?" <<>> The answer could be 'yes' if the body has a negative velocity as well as a negative acceleration (relative to a given system of coordinates). In that case the speed is increasing even though the acceleration is negative.
Which term explains wheather an objects velocity has increased or decreased over time?
Acceleration (a=v/t where a=acceleration, v=velocity and t=time; or Average acceleration= Δv/Δt, where Δv is the change in velocity and Δt is the change in time) shows the rate of change in velocity over time.If Acceleration (a) is positive, it means that velocity has increased over time and if it is negative, it implies the velocity has decreased over time [also commonly known as deceleration(-a)]
What is the objects change in speed called?
That's simply called a change in velocity. On the other hand, the rate of change in velocity - how quickly velocity changes - is called acceleration.
