4
Speed is always + ve​

Answer 1

Answer:

the wrong one is

displacement >distance

Answer 2

Velocity is always Positive.

Velocity is a vector. That means, it can be zero, positive or negative. It specifies both direction and magnitude.

More about velocity:-

• Velocity is known as displacement per unit time.

That is,

$\boxed{v = \frac{s}{t}}$

• It's SI unit is m/s.
• It is always equal to or less than speed.
• It's dimension formula is $M^0L^1T^{-1}$.

Formula of average speed:-

$\boxed{\overline{v} = \frac{Total \ ‘s’}{Total \ ‘t’}}$

s = Distance

Formula of average velocity:-

$\boxed{v_{av} = \frac{Total \ ‘s’}{Total \ ‘t’}}$

s = Displacement.
