When there is constant acceleration, what can you use?
SUVAT equations
What does r stand for?
new position
What does ro stand for?
initial position
What does s stand for?
displacement
What is the equation that includes, r, ro and s?
r=ro+s
What is the direction of travel determined by?
velocity
What does speed equal?
speed = IvI
V= 3i + 4j
how do you work out the speed and direction?
[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
What does it mean when travelling South West?
i component = -j component
