$(a)$ Define circular motion.
$(b)$ "Uniform circular motion is an accelerated motion". Justify this statement with reason.
$(c)$ An artificial satellite is moving in a circular orbit of radius $42250\, km.$ Calculate its speed if it takes $24$ hours to revolve once around the earth.
What is the nature of the displacement$-$time graph of a body moving with constant velocity ?
The numerical ratio of displacement to distance for a moving object is
