No, Speed is always greater than or equal to zero. However, velocity can be negative, which just means you have a positive speed in the opposite direction! (scalar(number) versus vector).
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.
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.
Impossible.
No.
Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.
Negative speed isn't possible, but negative velocity is.
Speed is (distance covered in some time) / (time to cover the distance).Neither the distance covered in the time, nor the time duration, can be negative.If you'll say "Well what about moving backwards ?", then you have introduced the directionof motion into the discussion, and now you're talking about velocity, not speed. Velocity caneasily be negative, but speed can't.
see speed cannot de negative se speed = distance / time and neithr distance nor time can be negative they r always positive so speed cannot be negative but velocity can be negative
yes, it is possible to have a negative decimal.
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.
It is believed that the speed of light is the highest possible speed.
Yes it is possible...
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.
No.
Impossible.
Radii are always positive. No, it is not possible to draw a circle with negative radius.
Acceleration is negative.
