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.)

When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).
Two words for what happens when an objects velocity decreases?
negative acceleration
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.
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
If an objects velocity time graph is a straight line parallel to the taxis what can you conclude about the objects acceleration?
acceleration is zero
How do you calculate an objects acceleration?
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
What happens to an objects speed if it travels with zero acceleration?
That means, of course, that the velocity (and the speed) doesn't change.
If objects get faster with time the direction of the acceleration is?
The acceleration is positive.
How are acceleration and velocity alike and different from each other?
-- both are related to measurements of motion of objects -- acceleration is the rate at which velocity changes
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)]
Mass is a measure of an objects resistance to?
To acceleration (change in velocity).
