Answers
Explanation:
1)in motion
2)rectilinear
3) curvilinear
4) rotatory
5)non uniform
Answer:
1)- Motion as a body aca nbe in motion only if it moves and its position is changing.
2)- rectilinear motion as Aa vehicle moving on a straight road changes its position every second, hence we can infer that the vehicle is in motion. Usually the motion of the bodies is categorized into two. One is the rectilinear motion and the other is the periodic motion.
3)- Moving Blades of a windmill is an example of Circular Motion. The Windmill is the machine that converts the wind energy into the rotational energy by the blades of the windmill.
4)- the wheels of a moving car have the same translatory motion as the car. In addition, each wheel has a rotatory motion about its own axis
5_)- the motion will be NON UNIFORM MOTION as since its a crowded place, the boy has to apply brakes or change the speed accordingly. Hence the motion becomes accelerated. So we can conclude its a NON uniform motion
