Below are sample questions representative of the exercises included on this worksheet and related 8.53 Kinetic Energy and Speed Mass skill assessments:

Problem 1Difficulty: Mastery

A graph and a table both describe the same object. The table shows kinetic energies 8 J, 32 J, and 72 J at speeds 2 m/s, 4 m/s, and 6 m/s. What should the graph look like?

AA straight line with equal rises

BA downward line

CA flat horizontal line

DAn upward curve that gets steeper

Solution & Explanation:The table follows a square pattern, so the graph should curve upward instead of forming a straight line.

Problem 2Difficulty: Mastery

A student compares two motions: same mass with speed changing from 5 m/s to 10 m/s, and same speed with mass changing from 5 kg to 10 kg. Which comparison shows the larger change in kinetic energy?

AChanging speed from 5 m/s to 10 m/s

BChanging mass from 5 kg to 10 kg

CBoth changes are equal

DNeither comparison changes kinetic energy

Solution & Explanation:Doubling speed multiplies kinetic energy by 4, while doubling mass multiplies it by 2.

Problem 3Difficulty: Mastery

A 10 kg object moves at 3 m/s. A second object has a mass of 5 kg. What speed must the second object have to have the same kinetic energy? Round your answer to the nearest hundredth of a meter per second.

Solution & Explanation:The first object has KE = 1/2(10)(3²) = 45 J. For the 5 kg object, 45 = 1/2(5)v² = 2.5v², so v² = 18 and v = √18 ≈ 4.24 m/s.
