What equation do you use to find velocity in a falling problem?

v = v0 +gt

What equation do you use to find height of a falling problem?

y = ½ at²

What equation do you use to find height of a falling problem?

x = V0t + ½ at²

What is V0 in a falling problem (not thrown down)

0

What equation do you use to find velocity in a thrown up in the air problem?

v = v0 + gt

What equation do you use to find height or time in a thrown up in the air problem?

y = y0 + v0 + ½ at²

What equation do you use to find max height in a thrown up in the air problem?

v² = V0² + 2ax

In a thrown up in the air problem what is v0?

not equal to 0. v0 = -v

What equation do you use to find horizontal distance in a ½ projectile problem?

x = v0t

What equation do you use to find vertical distance in a ½ projectile problem?

y = ½ gt²

What process do you use when doing a full projectile problem?

1. Trig - y: v0y = v0sin0; x: v0x = v0cos0

2. Time (vertical) - t = (v-v0)/g

3. Displacement (range = x & height = y) - x = v0t & y = ½ gt²
