Answer #1:
Constant speed is a speed that is maintained and stays the same.
Instantaneous speed is a speed that goes up momentarily and then
comes back down.
==================================
Answer #2:
A constant speed is one that has the same value now as it has had
at every previous time of interest, and the same as it will be for every
future time of interest.
An instantaneous speed is one that conveys no information about any
previous or future speed, only about the speed 'right now'.
I just made this up on the fly. I think it's pretty good.
Average speed is the total distance traversed divided by the total time required to get there.
Instantaneous speed is the speed at an instant in time and can be viewed as the distance traversed divided by the traversal time as the traversal time is made arbitrarily small. It can be written as a derivative.
In particular, velocity is a vector quantity
\vec v = \frac {d \vec x}{dt}
where \vec x is the (vector) displacement.
A displacement vector is a vector describing the difference in location from one point to another. A resultant vector is a vector that results from adding or subtracting vectors. A resultant vector can also be a displacement vector.
Both are velocity functions. Instantaneous velocity is the derivative of the average velocity

They are both speed functions. Velocity is a vector related to speed but quite irrelevant in this context. An object rotating at a constant [angular] speed has a velocity that is continuously changing but that has no relevance.
Speed is how fast you are going. Velocity is how fast you are going and what direction you are headed in.
Speed is a scalar (Only has magnitude, no direction)
Velocity is a vector (Has magnitude and direction)
Constant speed has no acceleration, whereas changing speed does.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
Constant speed is constant velocity which means your going a certain speed in a straight line. Speed is just your speed at an exact moment also called instantaneous speed
Velocity is speed with direction
Answer: No, the speed is constant, but the velocity changes, since the direction changes. Please be sure you understand the difference between "speed" and "velocity", as used in physics. Speed is scalar which has only magnitude but not direction Whereas velocity is having both. So is a vector quantitiy
The technical difference is that speed has no direction but velocity has one.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
Constant speed is constant velocity which means your going a certain speed in a straight line. Speed is just your speed at an exact moment also called instantaneous speed
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.

The technical difference is that speed has no direction but velocity has one.
velocity is speed with direction; velocity is a vector and speed is a scalar
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
Yes, speed is the scalar of velocity.
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
No. Velocity includes a direction vector, which speed does not have.
