Area under speed$-$time graph is equal to the
velocity of the body
magnitude of the displacement
distance travelled by the body
none of these
What is the numerical ratio of average velocity to average speed of an object when it is moving along a straight path ?
State the type of motion represented by the given graph.
$(a)$ Define acceleration.
$(b)$ A stone describes a circular path with a constant speed. State the type of motion of the stone.
Distinguish between terms speed and velocity.
A body can have zero average velocity but not zero average speed. Justify.
