Potential and Kinetic Energy

Introduction

This material is for students to use for learning about potential and kinetic energy

Task

The task is to learn and to answer the questions with yes or no about potential and kinetic energy using video material. The questions you answered with no please correct.

Process

When using this material the students should wach the video and then answer to the questions that are given.

The questions:

  1. Potential energy is do to position?
  2. Kinetic energy is do to motion?
  3. When talking abouth potential energy we use vebsity? 
  4. Is this 1/2*m*v the equation of kinetic energy?
  5. An object can have only potential or kinetic energy, these energys do not coexist in an object?
  6. Can a pendulum swing for ever becouse of the change between potential and kinetic energy?
  7. If your on top of the building you can use our potential energy on the way down?
  8. If a ball is thrown two times the first time vebsity is 25mph the second time vebsity is 45mph the second throws kinetic energy will be bigger? 
  9. Potential and kinetic energy measured in Joules?
  10. You can use potential and kinetic energy in different sports for instance pole vault?

Evaluation

You can get maximum of 20 points 2 points for each question. If the questions answer is yes you automatically get 2 points but if the questions answer is no you get 1 point for the answer and the second for writing the correction. 

The answers:

  1. Yes.
  2. Yes.
  3. No, when talking abouth potential energy we thin of mass(m), height(h) and gravity acceleration(g).
  4. No,  the equation of kinetic energy has vebsity squared.
  5. No, an object can have  potential or kinetic energy at the same time.
  6. No, becouse if lose energy in friction, heat and in sound.
  7. Yes.
  8. Yes.
  9. Yes.
  10. Yes.

Conclusion

You have finished the task and if you got:

20-19 points you have understood the theme and done your task very well

18-15 points you have understood the theme and done your task well 

14-10 points you have understood the theme

9-5 points  your points are below average if you want to understand this theme better you shauld watch the video again

4-1 points you do not understand have potential and kinetic energy works and you shaul watch the vidio again
