Question

If speed is variable then about velocity? Is it constant or variable? Please give answer

Answer 1

⊕ANSWER⊕

• So,velocity directly depend on speed but it's contain norms parameter.
• If speed is variable it means velocity must be variable and hence acceleration is also noon zero and may be variable.

NOTE :

• No, a body can never have its velocity constant, while its speed varies.
• ⭐EXPLANATION: Instead, it can have its speed constant and it's velocity varying as in a uniform circular motion.
• And in a uniform circular motion, the direction isn't the same always, instead it keeps changing.

Answer 2

Explanation:

Every unknown stuff is a variable . It's just that velocity is a vector quantity while speed is a scalar quantity .
