Kinematic Equations
v = at + u
v^2 = u^2 + 2as on formula sheet
s = ut + 1/2 at^2 on formula sheet
s = (u +v)t/2
8
New cards
Projectile motion
Vertical acceleration is -g or g (9.81)
Horizontal acceleration = 0
9
New cards
Terminal velocity
The greatest velocity a falling object can achieve.
Acceleration = 0
10
New cards
Derive v = at + u
11
New cards
Derive: s = ut + 1/2 at^2
12
New cards
Derive: v^2 = u^2 + 2as
