Let us recall some important concepts:



Speed & Velocity tell how fast an object travels and to what

direction it moves



If the object is at the rest, its speed is equal to zero.



If the object is moving at equal distance at equal interval of time,

the motion said to be constant.



If the object covers varying distances at equal interval of time, the

object is changing speed, and is therefore accelerating.

Reflection

Whenever you are on the road, you see a lot of traffic signs and symbols like

the one in the picture. Why do you think it is important to follow speed limit?

What could possibly happen if it were not followed? Does obeying a simple

traffic sign make sense for being a good citizen? Why? Why not? Write your

answer in your notebook. ​
