How can speed be decreasing but velocity be increasing of a certain object?

Speed is distance covered divided by time, while velocity is displacement divided by time. Velocity is a vector quantity while speed is not. An example of when speed would be decreasing yet velocity would be increasing occurs when a car driving in reverse slows down. If it was going 30m/s and then slowed town to 10m/s, the speed would be slowing down. However, since the car is moving along the negative x axis, its initial velocity vector would be -30m/s and it would decellerate to a velocity of -10m/s.
The example isn't great, but you can get the picture that the way that this is possible is by the fact that speed is a scalar quantity while velocity is vector.

When do you say that an object has an accelerated motion?
if its velocity is increasing or decreasing
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
increasing speed
How can you tell if an object is decelerating?
If the velocity is decreasing, the object is decelerating.
What can acceleration be described as?
Acceleration can be described as the rate at which an object's velocity changes over time. It measures how quickly the object's speed or direction is changing. Therefore, it quantifies how much an object's motion is increasing or decreasing.
If object moves with constant acceleration its velocity is?
It velocity is constantly increasing, v=vo + at.

increasing speed
How do you interpret how an object is moving from a distance time graph?
If the distance is not changing, the object is not moving. If the distance is increasing or decreasing linearly then the object is moving at a constant velocity. If the distance is increasing or decreasing parabolically then the object is being accelerated or decellerated.
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
How can you tell if an object is decelerating?
If the velocity is decreasing, the object is decelerating.
What is accomplished when an object is moved by a force?
When an object is moved by a force, work is done, increasing or decreasing its kinetic energy, often but not always decreasing or increasing its potential energy.
What is an velocity?
Velocity is the measure of increasing and decreasing speed. For example... on a velocity graph, if the object being measured is gradually getting faster the line will go up. If it is getting slower, it will go down, if it is staying at a constant speed, the line will be straight

What are the condtions for an object to stay at restto keep moving at constant velocity or to move with increasing velocity?
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
The speed of an object in a certain direction?
Velocity. Velocity also has a vector, or certain direction.
Distance an object travels in a certain direction in a certain time?
The velocity of the object.
