what quantities are represented by the terms "ut" and "1/2at^2"?
u = initial velocity
t= time
a= acceleration
s = displacement
(and v=final velocity) not used here

s = displacement
u = initial velocity
v = final velocity
a = acceleration
t = time
P.S. The suvat equations only work when acceleration is a constant

S - displacement
U - initial velocity
V - final velocity
A - acceleration (must be constant)
T - time
SUVAT!
Also another variation of that formula is
s = vt - 1/2at^2
yer but its not just "u" and "t", its "ut" and "1/2at^2" as a quantity isnt it?

"ut" represents the distance the object would have moved in a time of t seconds at constant velocity of u.
"½at²" represents the extra distance travelled as a result of the acceleration and increase in velocity from u to its final value.
Adding them together gives the total distance.

this is exactly what i needed
. Thanks a lot stonebridge

i know this is a really old post but thank you so much! was doing a past paper question for ocr physics unit 1 and the mark scheme didn't explain why they used 1/2 x 3.5 x t^2 and my response was: "what is this"
