What else can I help you with?
When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).
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.
Two words for what happens when an objects velocity decreases?
negative acceleration
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
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.
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.
What is the objects acceleration?
The acceleration of an object is the rate at which its velocity is changing over time. It is a vector quantity, meaning it has both magnitude and direction. Acceleration can be positive, negative, or zero, depending on whether the object is speeding up, slowing down, or maintaining a constant velocity.
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)
