Constant Acceleration Flashcards
1
Q
When there is constant acceleration, what can you use?
A
SUVAT equations
2
Q
What does r stand for?
A
new position
3
Q
What does ro stand for?
A
initial position
4
Q
What does s stand for?
A
displacement
5
Q
What is the equation that includes, r, ro and s?
A
r=ro+s
6
Q
What is the direction of travel determined by?
A
velocity
7
Q
What does speed equal?
A
speed = IvI
8
Q
V= 3i + 4j
how do you work out the speed and direction?
A
[3] (right 3=adjacent)
[4] (up 4=opposite)
you can draw out right angled triangle
speed = √(3)^2 + (4)^2 = 5ms-1
direction=tan-1 (4/3) =53.1° above positive x direction
