Unit 1 Test Review Speed, Velocity, and Acceleration

What is the formula for speed?

• Speed = Distance / Time
• Speed = Time / Distance
• Speed = Distance - Time
• Speed = Distance + Time

What is the formula for acceleration?

• a = (vf - vi) / t

• a = (vi - vf) / t

• a = (t - vf) / vi

• a = (vf - t) / vi

What is the difference between speed and velocity?

• Speed is always greater than velocity.
• Speed can be negative while velocity cannot.
• Velocity measures distance only, not direction.
• Speed is scalar; velocity is vector (includes direction).
