What else can I help you with?
What would cause an object to decelerate?
An object can decelerate due to forces acting in the opposite direction of its motion, such as friction or air resistance. Other factors such as gravity or changes in velocity can also cause an object to decelerate.
What are the requirements for an object to accelerate?
Velocity must be changing in order for an object to accelerate or decelerate.
What are two common terms for a decrease in velocity?
Deceleration and slowdown are both common terms used to describe a decrease in velocity.
How does velocity affect stoping?
Your velocity doesn't really affect your ability to stop. it just has an impact on how much you have to decelerate if you want to stop in a set amount of time. Assuming you decelerate at a uniform rate a from "a" speed "v" to a speed v = 0 you will do so in a time t = (v-0)/a = v/a
Which term explains whether an object's velocity has increased and decreased over time?
Acceleration is the term that explains whether an object's velocity has increased or decreased over time. Positive acceleration indicates velocity is increasing, while negative acceleration indicates velocity is decreasing.
When an object has a net force acting on it what happens to its velocity?
When an object has a net force acting on it, its velocity changes. The object will accelerate in the direction of the net force if the force is in the same direction as the object's velocity, decelerate if it's in the opposite direction, or change direction if the force is perpendicular to its velocity.
What orientation of velocity and acceleration will cause something to initially slow down?
When velocity and acceleration are opposite in direction (velocity forward and acceleration backward, or vice versa), the object will slow down initially. This is because the acceleration is acting in the opposite direction of the velocity, causing the object to decelerate.
Why is velocity changing?
Velocity can change due to a change in speed or direction of an object. It can also change if there is a force acting on the object, causing it to accelerate or decelerate. In simpler terms, velocity changes when an object speeds up, slows down, or changes direction.
When Velocity of particle equals average velocity equals instantaneous equals speed is possible?
When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.
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)]
When the velocity of an object changes it is acted upon by a (n)?
When the velocity of an object changes, it is acted upon by a force. This force can be due to various factors such as gravity, friction, or applied external forces. The force causes the object to accelerate or decelerate, resulting in a change in its velocity.
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
