Velocity is ...

• speed with direction

• speed with time

• speed with distance

• speed with acceleration

The scalar form of displacement is

• distance

• speed

• acceleration

• time

Which one is missing final speed?

• d = v₀ t + ½ a t²

• v = v₀ + a t

• v² = v₀² + 2 a d

• (v + v₀) / 2 = d / t

Which one is missing time?

• d = v₀ t + ½ a t²

• v = v₀ + a t

• v² = v₀² + 2 a d

• (v + v₀) / 2 = d / t

Which one would you not use to find flight time?

• d = v₀ t + ½ a t²

• v = v₀ + a t

• v² = v₀² + 2 a d

• (v + v₀) / 2 = d / t

Which one is missing distance?

• d = v₀ t + ½ a t²

• v = v₀ + a t

• v² = v₀² + 2 a d

• (v + v₀) / 2 = d / t

In free-fall, the only force considered is

• friction

• force due to gravity

• air resistance

• applied force
