look like when it is in uniform
motion?

Answers
Answer:
1. Velocity is a vector quantity bit speed is a scalar quantity.
2.when a object moves along a straight path with out change in its direction, then the average speed of an object is equal to it's average speed
3. odometer of an automobile measures the distance travelled
4.it looks like the object is traveling in a straight path or lineI don't know this answer sorry for that.
5. I m sorry I don't know this answer
Ans 1 : Speed, being a scalar quantity, is the rate at which and object covers distance. the average speed is the distance per time ratio. speed is ignorant of direction. On the other hand, velocity is a vector quantity; It is direction aware.
Ans 2 : Odometer, or odograph , is a device that measures the distance travelled by an automobile based on the perimeter of the wheel has the wheel rotates.
