We can, but it is fairly redundant. The only component that is limited is the speed, not the direction, so it is pointless to say that we have not limited the direction and thus we only say the 'speed limit'.
Yes, it is correct to refer to speed limit signs instead of velocity limit signs because "speed" specifically refers to how fast an object is moving, regardless of its direction, while "velocity" includes both speed and direction. Traffic regulations focus on the rate of motion rather than the directional aspect, making "speed limit" the appropriate term for these signs. Additionally, using "speed" is more widely understood by the general public.
it's velocity...it's velocity...
There is no limit.
There is no term limit for the governor of Minnesota.
The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
Velocity
velocity
Velocity is a speed in a very specific direction.
Acceleration is the scientific term for change in velocity.
A change in velocity is known as acceleration .
