Equations Flashcards
what is the equation to workout linear velocity?
displacement / time
or
final displacement - initial displacement / time
What is the equation to workout linear displacement?
velocity x time
What id the equation to workout out time when given the displacement and linear velocity?
displacement / velocity
How is displacement found?
pf - pi
How would you rearrange Pythagoras theorem to make c the subject?
C= √A²+B²
what is the equation for Pythagoras theorem?
A² + B² = C²
How would you rearrange pythagoras theorem to make a and b subject?
A²=B²+C²
B²= A²-C²
What is the equation for acceleration?
Velocity / Time
What would be the equation for velocity when given acceleration and time?
acceleration x time
What would be the equation for time when given acceleration and velocity?
velocity / acceleration
What are the 5 SUVAT equations?
v = u+at
s=½(u+v)t
s=ut + ½at²
s=vt - ½at²
v²= u² + 2as
In the equation v=u+at. How would the equation be rearranged to make a the subject?
a= v-u / t
What are the equations for right angled triangles?
sinθ= o / h
cosθ= a / h
tanθ= o / a
h²= a² + o²
What are the values for acceleration due to gravity in both directions?
down = +9.81m/s
up= -9.81m/s
what is the equation for speed?
distance / time
