'The Big 5 Equations' Flashcards
The second equation.
Known as ‘the definition of average Velocity’
Used when acceleration is constant
/\d = 1/2(Vi + Vf) /\t
Can also be rearranged to read:
/\d
___ = 1/2(Vi + Vf)
/\t
The Third equation.
Known as ‘The Classic’
Tale end of equation from calculus.
/\d = Vi ( /\t ) + 1/2a(/\t)^2
‘Delta D equals initial velocity multiplied by time, plus one half times acceleration multiplied by time squared’
The Forth equation.
Known as the 3rd equation part 2.
Second half of equation is from calculus.
/\d = Vf ( /\t ) - 1/2a(/\t)^2
‘Delta D equals final velocity multiplied by time, minus one half times acceleration multiplied by time squared’
The Fifth equation.
Known as ‘the tale of two squares’
Works off of mathematical principal of ‘difference of squares’
Vf^2 = Vi^2 + 2a/\d
‘Final velocity squared equals initial velocity squared, plus 2 times acceleration times delta displacement’
The first equation.
Equation has unknown variable /\d
Known as the ‘definition of acceleration’
Vf - Vi
___________
A = /\t
Also written as:
/\ V A = \_\_\_\_\_\_\_\_\_\_
/\ t
Kinematics Equations tells us:
Tells us ‘How stuff moves’
-when acceleration is constant (uniform motion)
