8.1 Motion Check Your Understanding Questions #All



1. Scalar Quantity: Is a quantity that describe magnitude, but do not include direction are called scalar quantities or scalars.

2. Vector Quantity: A vector quantity includes both a magnitude and a direction.

3. Magnitude refers to the size of measurement or the amount of the number you are counting.

4. Position is and actual position that someone may be in at the time, while distance is how far something or someone has traveled.

5.
(a) Distance=Scalar
(b) Time intervals=Scalar
(c) Position=Vector
(d) Displacement=Vector







7. The mathematical difference is time interval.

8. Delta

9. Displacement describes the straight point distance and direction from one place to another.

10. Velocity * Time

11. The object would have traveled 4m because it was uniform which means the object would have stayed the same constant speed all the way.

12.
(a) The Position

(b) The Time

13. A straight one on a 45o angle.

14.
(a) 6m North
(b) 7m East
(c) 6m South

15.
(a) 6m east

(b) 6m east

(c) 6m west

(d) 0m

16. 12 m the object traveled in 10 s.

17. Unless it travels in a straight line.
