the speed at which a variable changes over a specific period of time
It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.
No, a constant velocity means that there is no change in speed but there can still be a change in direction, which would lead to a change in momentum since momentum is a vector quantity that considers both speed and direction.

Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
yes
It means something that doesn't change, like a number.
The change in y over the change in x
No
Invariably means constant and not prone to change, and can mean always.
Constant just means that the number does not change. For example, in Chemistry, avogadro's number is 6.022x10^23 and that number will never change, therefore it is a constant.
Nothing stays the same for ever.
if a number can change randomly it is called a variable
The variable will change at a constant rate. Its pattern will never be broken or changed throughout its process.
the object's speed doesn't change
A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)
It is called a constant and it value remains the same.
