No, they don't. Velocity is a vector - made up of both a magnitude (number), and a direction. If any of the two changes, the velocity is not the same.
If you are interested only in the magnitude, you talk about "speed", not "velocity".
Darth Maul's double light saber because the rays from the light saber are going 2 different directions.
No. It's confusing unless you're into physics or mathematics but velocity is a vector quantity with speed is one aspect. Velocity includes speed and the direction of motion. A car is going 60 miles per hour as speed. A car is going 60 MPH due north is velocity.
Yes velocity is a vector that has both speed and direction. So if you are going 30 mph in one direction that may be positive, but if you are going in reverse that may be negative.
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
No. Velocity is a vector, so it has both a magnitude and a direction. If the velocity of your car was heading in the positive direction, then the other car is moving in the negative direction. The velocities are NOT the same!
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
To find the resultant velocity when combining two velocities going in opposite directions, you simply subtract the smaller velocity from the larger velocity. The direction of the resultant velocity will be in the direction of the larger velocity.
The resultant velocity is found by subtracting the smaller velocity from the larger one if they are in opposite directions. This is because the velocities are working against each other to some degree, resulting in a net velocity that is the difference between the two.

The diagram you are asking for looks like two lines, with the same length, but pointing in two different directions. The difference in direction is what would show the different velocity. So imagine one line going down, one like going right, same length, but directions, so they would be different velocities.
Its ovious why a compass points in different directions. For example, if your going north, the compass points north because your going that direction. Theres also a magnet concealed in the compass. How does the compass know what direction yoiur going. Earth it self is a magnet. When you head that direction, it will point
It's positive in the direction of the greater one, and negative in the direction of the smaller one.
It stops going only one way and starts going every which way.
Velocity is speed plus direction. If you say you are traveling at 54 miles per hour, you are giving your speed. If you say you are going north at 54 miles per hour, you are giving your velocity.
The average velocity is trying to find how fast the car is going at an average rate. However, constant velocity means that the car is going at an unchanged velocity. Say a car is going at 75 m/s and then changes to 50 m/s and then changes to 25 m/s in 30 minutes. The car is going at different velocities at different times. To find the average, you simply just add the 3 together, then divide by 3 giving you, 50 m/s In the 30 minutes, it's average velocity was 50 m/s However, for a car going at a constant velocity, it means that the velocity never changes. Say a car is going at a constant velocity for 30 minutes at 50 m/s. In those 30 minutes, the car will never change it's velocity and remain at 50 m/s. Constant means that it doesn't change.
Where are you and where are you going.
That's going to depend on the directions of each of the two initial velocities. It's also going to depend on who measured the initial velocities, where he was standing, how he was moving, and with respect to what else, etc.
