Uniformly Accelerated Motion Quiz

What is the acceleration due to gravity on the earth's surface?

• 6.67 m/s^2

• 15.2 m/s^2

• 12.5 m/s^2

• 9.81 m/s^2

What is the formula for average velocity between two points?

• v = (y1 - y2) / (t1 - t2)

• v = (y3 - y2) / (t3 - t2)

• v = (y2 - y3) / (t2 - t3)

• v = (y2 - y1) / (t2 - t1)

What is the value of the constant acceleration for an object in free fall?

• 9.81 m/s^2

• 6.25 m/s^2

• 11.3 m/s^2

• 8.45 m/s^2

What is the formula for calculating average acceleration?

• a = (v23 - v12) / (t23 - t12)

• a = (v12 - v23) / (t12 - t23)

• a = (v23 + v12) / (t23 + t12)

• a = (v12 + v23) / (t12 + t23)
