Stepping Up with PE and KE - Questions

The Stepping Up with PE and KE Concept Builder is comprised of 3 Difficulty Levels. Each Difficulty Level presents a unique motion scenario with numerical values for mass and height. Students must analyze the motion to determine the PE and KE values at three or more specified locations along the path. Students are told to assume mechanical energy conservation. There are three sets of PE and KE values for the Apprentice Difficulty Level. The Master Level includes 4 sets of PE and KE values and the Wizard Level includes 5 sets of PE and KE values. Numerical values of mass and height are chosen at random from a list of permitted values. Given the random nature of question generation, it is difficult to list all the possible combinations of mass and heights. 

The number of misses are tracked and used to determine a Health Percentage. The Health Percentage is reported once the analysis is complete. Students have the option of repeating the Difficulty Level in order to improve their Health Percentage.

The 3 different difficulty levels are shown below. Teachers are encouraged to view the levels in order to judge which level(s) of difficulty is(are) most appropriate for their classes.

Stepping Up with PE and KE


Note: There is only one question with multiple blanks in each Difficulty Levels. The numerical values that are in the question are selected at random from a large bank of possible values. As such, two side-by-side students are unlikely to have identical questions. We are showing just one of the many possible values in the problems below.

 
Activity 1: Apprentice Difficulty Level
Consider the 3-step staircase. All steps provide an equal elevation gain. The potential energy (PE) on the top step is 45.0 J. Determine the PE and KE values of the ball at the indicated positions.
 
 
PE1(J): __________
PE2(J): __________
PE3(J): __________
PE4(J): __________
KE4(J): __________
 
 
 
Activity 2: Master Difficulty Level
Consider the 4-step staircase. All steps provide an equal elevation gain. The potential energy (PE) on the top step is 44.0 J. Determine the PE and KE values of the ball at the indicated positions.
 
 
PE1(J): __________
PE2(J): __________
PE3(J): __________
PE4(J): __________ 
PE5(J): __________
KE5(J): __________

 
Activity 3
Consider the 5-step staircase. All steps provide an equal elevation gain. The potential energy (PE) on the 4thstep is 36.0 J. Determine the PE and KE values of the ball at the indicated positions.
 

 
 
PE1(J): __________ 
PE2(J): __________ 
PE3(J): __________
