SUVAT

When can you use SUVAT equations?

• Any time you want to find speed, displacement, time, velocity or acceleration

• When acceleration is constant

• When acceleration is variable

• Any time when you are treating an object as a particle

What does 's' stand for in the SUVAT equations?

• speed

• displacement

• distance

• velocity

What does the letter 'v' stand for in the SUVAT equations?

• Speed

• Initial velocity

• Final velocity

• Variable

Which of these is a correct SUVAT equation

• v = u + 2as

• v = u + at

• s = vt + 1/2 at^2

Which of these is a correct SUVAT equation?

• v² = u² + at

• s = (u + v)t

• s = ut - 1/2 at^2

• v² = u² + 2as
