lesson 3- uniform motion & speed Flashcards
(10 cards)
1
Q
how can we analyze motion of an object?
A
comparing its position to another point
2
Q
reference point
A
other point for observations in uniform motion
3
Q
motion
A
imaginary line joining an object to reference point changes in length or direction or both.
4
Q
uniform motion
A
describe object travelling at a constant rate of motion in a straight line
5
Q
does uniform motion exist in the real world?
A
no
6
Q
average speed
A
distance an object travels in specified time
6
Q
average speed =
A
distance travelled (m)/ time elapsed (s)
7
Q
slope
A
rise/ run or y2-y1/ x2-x1
8
Q
a greater or steeper slope indicates a
A
faster speed!
9
Q
a lesser slope indicates a
A
slower speed
