Unit of impulse
A
Ns
10
Q
Impulse momentum theory
A
ft = mv
(Impulse = momentum)
11
Q
Conservation of momentum
A
m₁v₁ + m₂v₂ = m₁u₁ + m₂u₂
(total momentum before = total momentum after)

(change in velocity) ; (change in time)
17
Q
Final velocity
given vi, g & t
A
Vf = Vi - gt
18
Q
Distance
given vi, g & t
A
d = Vi(t) - 1/2gt^2
19
Q
Final velocity
given vi, g & d
A
Vf^2 = Vi^2 - 2gd
20
Q
