cruising speed
The answer is that u r travelling with an average speed for that time or a constant speed . it also means that u are travelling with a uniform velocity.
As long as all the light is traveling through the same stuff, all colors have the same speed.
as long as they are both traveling through the air, then the speed is the same.
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Speed. All photons traveling through a vacuum travel at the speed of light.
ANY light traveling through the same medium (stuff) has the same speed.
Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.
No, since it's a vector quantity and has direction. The two automobiles will have the same absolute value, but will be the negation of one another, for example 50 and -50.
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.
constant speed
Speed and velocity have both changed.
the same as you were if you weren't.
