What else can I help you with?
Does velocity stay the same when speed and direction stay the same?
Yes, velocity remains the same when both speed and direction remain constant. Velocity is a vector quantity that includes both speed and direction, so as long as both are unchanged, the velocity will remain constant.
Why do you lose your hair when you lose weight?

How long a water rocket stay in air?
The duration a water rocket stays in the air can vary based on the pressure level in the rocket, the design of the rocket, and external factors such as wind speed. On average, a water rocket can stay in the air for around 5 to 20 seconds.
Why doesn't your hair stay straight permently after you straighten it?
When you straighten your hair using heat styling tools, the heat temporarily changes the hydrogen bonds in your hair and rearranges them into a straighter pattern. However, once your hair gets wet or is exposed to humidity, the hydrogen bonds return to their original state, causing your hair to revert back to its natural texture. This is why straightened hair doesn't stay straight permanently.
Why friction is independent of speed?
Friction is independent of speed because it is primarily caused by microscopic irregularities on the surfaces of objects coming into contact, rather than any motion-related factors. As long as the surfaces remain in contact, the level of friction will stay relatively constant regardless of the speed at which the objects are moving.
