Projectile Motion and Velocity Components

v meters per second

g meters per second

h meters per second

d meters per second

y = vt

y = h - 1/2 gt^2

x = h - 1/2 gt^2

x = vt

t = sqrt(h/2g)

t = h/g

t = 2h/g

t = sqrt(2h/g)

90 degrees

45 degrees

135 degrees

180 degrees

v = g/t

v = gt

v = g + t

v = t/g

d = 3h

d = h/2

d = 2h

d = h

Using 180 degrees instead of 135 degrees

Using 45 degrees instead of 135 degrees

Using 90 degrees instead of 135 degrees

Using 0 degrees instead of 135 degrees

Writing t = 2h/g instead of t = sqrt(2h/g)

Writing t = h/g instead of t = sqrt(2h/g)

Writing t = sqrt(2h)/g instead of t = sqrt(2h/g)

Writing t = sqrt(h/2g) instead of t = sqrt(2h/g)

Ignoring the negative sign in velocity

Misinterpreting the direction of velocity

Using incorrect units for velocity

Confusing horizontal and vertical components
