There are two parts to acceleration: direction and speed. When either of these aspects are changed, then acceleration changes.

Disscuss the relationship between velocity and accleration?
accleration is the speed. Velocity is when you know the speed of an object and its direction.
What are two types of accleration?
Changes in speed or direction
What is the equation for accleration?
Acceleration = change in velocity/time for the change in the direction of the change.
When a falling object has reached its teminal velocity its accleration?
When the velocity stops changing, then, by definition, the acceleration is zero.
When cars are changing direction they are also changing what?
They are changing velocity. Velocity is the measure of speed and direction
Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
Can you control sound wave direction by changing the direction and presure of air?
You can control sound wave direction, by changing the direction and pressure of air.
Can a body posses velocity when its accleration is zero?
Of course. You need to go back and review the definitions of those terms. Acceleration is the rate at which velocity changes. If velocity is not changing, then there is no acceleration. But the velocity doesn't have to be zero just because it's not changing. Velocity is the speed of an object and the direction in which it's moving. If it's moving at a constant speed in a straight line, then it has plenty of velocity. But since the speed isn't changing and the direction isn't changing, there's no acceleration. If acceleration comes along somehow ... such as by igniting a rocket motor, or gravity pulling the object downward, or someone reaching out and giving the object a push, then the speed or direction may change, and that'll be a change of velocity.
When an object increases in speed what does the accleration vector do?
An object with an increasing speed is in fact accelerating, hence the acceleration vector may be continually changing (but >0) with time.
If you speed is not changing but your direction is changing are you accelerating?
Yes; acceleration is any change in velocity - speed, or direction.
What is the opposite of changing direction?
The opposite of changing directions would be maintaining a course, or continuing in the same direction.
Which is the ability to maintain control while changing direction?
Agility-The ability to maintain control while changing direction
