Question

(N/A) Differences between speed and velocity:$1$. Speed is the distance traveled per unit time,whereas velocity is the displacement per unit time.$2$.

Vedclass · Accepted Answer

Uniform velocity: When a body covers equal displacements in equal intervals of time in a fixed direction.

Vedclass · Answer

(N/A) Differences between speed and velocity:$1$. Speed is the distance traveled per unit time,whereas velocity is the displacement per unit time.$2$. Speed is a scalar quantity (has only magnitude),whereas velocity is a vector quantity (has both magnitude and direction).$(a)$ $A$ body is said to have uniform velocity if it covers equal displacements in equal intervals of time in a fixed direction.$(b)$ $A$ body is said to have variable velocity if it covers unequal displacements in equal intervals of time or if its direction of motion changes.When the velocity of a body changes at a non-uniform rate,the average velocity is calculated by taking the arithmetic mean of the initial velocity $(u)$ and the final velocity $(v)$:$	ext{Average Velocity} = \frac{u + v}{2}$

List two differences in tabular form between speed and velocity. When is a body said to have: $(a)$ uniform velocity and $(b)$ variable velocity? How is the average velocity of a body calculated when its velocity changes at a non-uniform rate?
