Projectile Motion

There are 4 types of projectile motion questions. For all 4 types, we use the big five to solve them.
Type 1:
x:                             y:


ax = 0                      ay = gravity = 9.8m/s^2

vx is constant           vy = 0

dx = (vx)(tx)            dy = height

Time is equal for both x and y

Type 2:
x:                                   y:


ax = 0                            ay = gravity = 9.8m/s^2

vx = v1cos(θ)                vy = v1sin(θ)

dx = Range                    dy = 0

Time is equal for both x and y

Type 3 & 4:
These two are similar to Type 2. The only difference is that Type 3 has a positive dy and Type 4 has a negative dy.
