MCAT Translational Motion Quiz

What is the primary difference between speed and velocity?

• Speed and velocity are the same.

• Speed is a vector and velocity is a scalar.

• Speed has direction while velocity does not.

• Speed is a scalar and velocity is a vector.

Which formula correctly represents speed?

• Speed = time/distance

• Speed = distance/time

• Speed = displacement/time

• Speed = velocity/time

In the context of physics, what does the delta symbol (Δ) represent?

• The sum of two quantities

• The product of two quantities

• The difference between two quantities

• The average of two quantities

How do you solve for the final position (X) in the equation V = (Xf - Xi)/t?

• Xf = Vt + Xi

• Xf = Vt - Xi

• Xf = Xi + Vt

• Xf = Xi - Vt

What is the formula to calculate average velocity?

• Average velocity = (V1/V2)/2

• Average velocity = (V1 - V2)/2

• Average velocity = (V1 + V2)/2

• Average velocity = (V1 * V2)/2

If a girl walks 1.4 miles in 20 minutes, what is her speed in miles per minute?

• 0.05 miles per minute

• 0.10 miles per minute

• 0.14 miles per minute

• 1/20

What is the estimated value of 7/200 using estimation techniques?

• 0.030

• 0.033

• 0.040

• 0.035
