Question

Which statement about speed and/or velocity is true?

Velocity has both speed and direction.

Speed is constant.

Speed has direction and velocity.

Speed is measured over time.

Answer 1

Answer:

Velocity has both speed and direction.

Explanation:

speed is a part of velocity

Answer 2

The statement about speed and/or velocity which is true is: Velocity has both speed and direction.

Velocity refers to the rate of change in displacement (distance) with time. Velocity is a vector quantity and this simply means that, it has both magnitude (speed) and direction.

Mathematically, velocity is given by the formula;

$Velocity = \frac{Distance}{Time}$

On a related note, speed is a scalar quantity because it has magnitude but no direction.

However, both speed and velocity are measured in meters per seconds.

In conclusion, the relationship between speed and velocity is that velocity has both speed and direction.
