A
Sn = u + a/2(2n - 1)
2
Q
Area under vt gives
A
displacement
3
Q
Area under vt gives
A
distance
4
Q
Area under at gives
A
change in V
5
Q
at height H, V =
A
√2gH
6
Q
at height H, V & time of fall is independant of
A
mass
7
Q
Time of fall
A
t = √(2H/g)
8
Q
When obj is thrown upwards, a =
A
-g
9
Q
At max H, V =
A
0
10
Q
H(max)
A
u^2/2g
11
Q
Time of flight
A
T = 2t t = time of fall
12
Q
S =
A
αβt^2/2[α+β] where α, β are acc at time t1, t2
13
Q
tanα =
A
Bsinθ/ A + Bcosθ
14
Q
if |A| = |B|, then |R| =
A
2Acosθ/2 = |A+B|
