An object ALWAYS has velocity, although the velocity may be zero for most of the time, or even all the time.
'Velocity' means the object's speed AND the direction in which it's moving.
As long as the girl stands and holds the ball in her hand, the ball's velocity is zero. As soon as she drops it out of her hand, it starts having velocity that's not zero.
While it's bouncing, its velocity is . . .
== growing and downward while it's falling from her hand toward the ground,
== zero for the instant of time when it hits the ground and changes direction from down to up,
== shrinking and upward while it's rising from the ground to her hand,
== zero for the instant of time when it hits her hand and changes direction from up to down.
It’s GAT because I just learned about this

Answer:
If the Kelvin temperature of a gas is increased, the volume of the gas increases. This can be understood by imagining the particles of gas in the container moving with a greater energy when the temperature is increased.
Explanation:
If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure. Conversely if you cool the molecules down they will slow and the pressure will be decreased.
To calculate a change in pressure or temperature using Gay Lussac's Law.
Well, first off, Newtons second law of motion <span>deals with the motion of accelerating and decelerating objects.
W</span>e already know that from everyday life examples such as simply pushing a car that if 2 people push a car on a flat road it will accelerate faster than if one person was pushing it... Therefore, there is a relationship between the size of the force and the acceleration.
Now onto the third law of motion. First of all, what is the third law of motion? Well, a force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions! According to Newtons third law, whenever one object, and another object interact with each other, they exert forces upon each other. "For every action, there is an equal and opposite reaction." The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. So, how is this important to everyday life you may ask?
<span>Well, the action-reaction force pairs are found everywhere in your body.
For example, right now as I am typing, my tendons are exerting forces on bones, and those bones exert reaction forces on the tendons, as muscles contract, pulling my fingers on the keys. I press on those keys, and they press back on my fingers. See? Since i'm pressing on the keys, the press back on me. Its opposite from each other, as stated in the quite above. "</span><span>For every action, there is an equal and opposite reaction." </span>
