Mini LAB VECTOR 1D
FIRST WATCH THE MOVIE.
1) A chicken stands on a road. Is it moving ? ________ the answer depends on the
____________________________.
2) If you are in a train, moving at a constant speed (straight line) .
You watch another train through the window.
Can you tell if it is your train that is moving or the other train ? ____
(principle of relativity found by Einstein)
3) Any motion is relative to the observer’s _________________________.
4) A chicken crosses a 8 wide road 4 times. (he moves back and forth, starts from a given point). How far has it moved ? There are 2 answers. ______ and _______
5) In Physics, we define the motion as a change in ______________ relative to a __________________.
6) displacement is the change in ______________ in __________________.
Distance is the total change in ______________ with no ______________.
7) scalar quantities are define by their ___________________. They do not involve any ___________.
8) vector quantities require a ________________ and a ________________.
A vector tells how much (magnitude), of what (units) and in which ___________ .
For example, weight is a ___________. It has a __________ and a direction.
The direction is ________. What are the 2 forces acting on a sky divers ?
____________ and ___________. What are their directions ?
9) Give examples of scalar quantities.
10) In the list shown in the movie, which scalar quantities can be vectors if given directions ? Velocity is a _________ with a direction. Displacement is a _________ with a direction.
Velocity tells you how fast but also in _________ something is moving.
11) If this is 3m@east :
Find the following vectors.
12) use a protactor, a ruler to find these vectors. 1 cm = 1m
Find the magnitude and the direction. (like shown in the movie)
13) Draw:
A) 12 W of S E) 33 S of E
B) 40 N of E F) 15S of W
C) 24 E of N G) 30N of W
D) 3W of N H) 19E of S
14) A student walks (from home) to school 8 blocks east of home. He returns home for lunch and goes back to school. His displacement is ….. .
15) Which of these is a vector quantity?
Temperature? mass? weight? Area?
