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 is calculated when its velocity changes at a non$-$uniform rate ?
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 is calculated when its velocity changes at a non$-$uniform rate ?
For difference see chapter at a glance.
$(a)$ If a body covers equal distances in equal intervals of time in a given direction.
$(b)$ When a body travels unequal distances in equal intervals of time or its direction changes or both change.
Average velocity will found out by finding the ratio (Net displacement$/$net time).
