Mrs. Smith is teaching a science class. She holds a pendulum and pulls the ball at the end of the pendulum to position A. Then she lets it swing to position G. The picture below shows the starting position A, the ending position G, and several positions in between the start and the end. The arrow shows the direction of motion. Think about the motion of the pendulum as you answer the questions. Question 1 a. At position A, describe the energy of the pendulum ball.(1 point) Responses Kinetic energy and potential energy are both at their lowest values. Kinetic energy and potential energy are both at their lowest values. Kinetic energy is at its highest value, while potential energy is at its lowest value. Kinetic energy is at its highest value, while potential energy is at its lowest value. Potential energy and kinetic energy are both at their highest values. Potential energy and kinetic energy are both at their highest values. Potential energy is at its highest value, while kinetic energy is at its lowest value. Potential energy is at its highest value, while kinetic energy is at its lowest value. Question 2 b. Drag the terms (listed below the paragraph) into the blanks in order to correctly complete the paragraph. You will use the terms more than one time each. (2 points) Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left
arrow key, or right arrow key. Let's go! At position A, the pendulum ball has _______ energy and _______ energy. As it swings to position G, the potential energy _______ and the kinetic energy _______. The pendulum ball reaches its _______ potential energy and _______ kinetic energy at position G.
Terms:
- highest
- lowest
- increases
- decreases
- greatest
- lowest
Question 1 a. At position A, the energy of the pendulum ball is:
Kinetic energy is at its highest value, while potential energy is at its lowest value.
Question 2 b. The terms to be dragged into the blanks are:
- Kinetic energy
- Potential energy
The correct completion of the paragraph is:
At position A, the pendulum ball has __Kinetic energy__ and __Potential energy__ at their highest value.
Question 1: At position A, the energy of the pendulum ball can be described as follows:
Kinetic energy and potential energy are both at their lowest values.
Explanation: At position A, when the pendulum ball is pulled to one side, it is at its highest point in the swing. Therefore, the ball has the least amount of potential energy, as it is furthest from the ground. Additionally, since the ball is momentarily at rest, it has no kinetic energy.
Question 2: In order to complete the paragraph, you will need to drag the terms listed below into the blanks. These terms should be used more than once.
Responses:
- Kinetic energy
- Potential energy
Explanation: To complete the paragraph, you need to insert the terms "kinetic energy" and "potential energy" into the blanks.
The correct completion of the paragraph would be:
"At Position A, the pendulum ball has the least amount of _______________ and _______________. As the ball swings from position A to position G, the _______________ energy of the ball increases while the _______________ energy decreases."
You can select the terms and insert them into the blanks using the space bar or enter key. The terms "kinetic energy" and "potential energy" should be inserted into both blanks, as the energy values are both at their lowest at position A.
