Which statements about velocity are true?


Check all that apply.

AThe SI units of velocity are m/s.
BFor velocity, you must have a number, a unit, and a direction.
CTo calculate velocity, divide the change in the distance by time.
DThe symbol for velocity is .

AMetre per second (m/s) is an SI derived unit of both speed and velocity.
TRUE
b)to find the velocity, you need the distance that something travelled in a given amount of time. It is a very useful number because it tells you how far something will travel in a given amount of time. Direction is also required.
i think it is true.
c) can't be.
d) the symbol of velocity could be v, u , or c. im not sure about '.'
correct me if im wrong.

Answer

A. The SI units of velocity are m/s.

B. For velocity, you must have a number, a unit, and a direction.


Explanation

Velocity is the rate of change of displacement. Velocity unlike speed it is a vector quantity. This means that it has both direction and magnitude. The SI unit of displacement is metres while that of time is seconds. So, the SI units of velocity will be Metres per second. From the choices in the question the statements that are true about velocity are ;

A. The SI units of velocity are m/s.

B. For velocity, you must have a number, a unit, and a direction.
