Questions and Answers

1.

Is the following statement TRUE or FALSE? Energy is never lost. It is only transferred or transformed.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Energy is never lost because of the principle of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed from one form to another. This means that even though energy may change from one form to another, the total amount of energy in a closed system remains constant. Therefore, the statement is true.

What is the MAIN form of Energy the skater has at POINT A in the Diagram?
- A.
  
  Gravitational Potential Energy
- B.
  
  Elastic Potential Energy
- C.
  
  Thermal Energy
- D.
  
  Sound Energy
Correct Answer
A. Gravitational Potential Energy

Explanation
At Point A in the diagram, the skater is at a height above the ground. Gravitational potential energy is the energy possessed by an object due to its position in a gravitational field. Since the skater is at a height, they have gravitational potential energy, which is the main form of energy at Point A. Elastic potential energy is associated with the stretching or compressing of an object, thermal energy is related to the heat of an object, and sound energy is produced by vibrations. None of these forms of energy are relevant to the skater at Point A.

What is the Energy transformation that occurs as the skater moves from POINT A to POINT B on the diagram"
- A.
  
  GPE to Kinetic Energy
- B.
  
  Kinetic Energy to GPE
- C.
  
  Elastic Potential Energy to Kinetic Energy
- D.
  
  GPE to Thermal Energy
Correct Answer
A. GPE to Kinetic Energy

Explanation
As the skater moves from POINT A to POINT B on the diagram, the energy transformation that occurs is from gravitational potential energy (GPE) to kinetic energy. Initially, at POINT A, the skater has a certain height and therefore possesses GPE. As the skater moves downwards towards POINT B, the GPE is converted into kinetic energy, which is the energy of motion. This transformation occurs due to the force of gravity acting on the skater, causing them to accelerate and gain speed as they descend.

Which is the correct statement below?
- A.
  
  At POINT C the skater has LESS Kinetic energy but MORE GPE than at POINT B
- B.
  
  At POINT C the skater has MORE Kinetic energy but LESS GPE than at POINT B
Correct Answer
A. At POINT C the skater has LESS Kinetic energy but MORE GPE than at POINT B

Explanation
At Point C, the skater has less kinetic energy because kinetic energy is dependent on the speed of the skater, and at Point C the skater is moving slower compared to Point B. On the other hand, the skater has more gravitational potential energy (GPE) at Point C because GPE is dependent on the height of the skater, and at Point C the skater is at a higher elevation compared to Point B.

What is the energy transformation that occurs in the Toaster Diagram shown?
- A.
  
  Electrical Energy to Heat, kinetic and sound energy
- B.
  
  Electrical Energy to kinetic and sound energy
- C.
  
  Kinetic energy, heat and sound energy to Electrical Energy
Correct Answer
A. Electrical Energy to Heat, kinetic and sound energy

Explanation
The correct answer is "Electrical Energy to Heat, kinetic and sound energy." In a toaster, electrical energy is converted into heat energy through the heating elements, which then heats up the bread. The kinetic energy is produced when the bread is toasted and pops up from the toaster. Additionally, sound energy is generated as a result of the toaster's mechanism and the popping sound of the bread.
