Sample questions

1. When a spring is stretched, what kind of energy is stored in it?

   1. Kinetic energy
   2. Potential energy
   3. Thermal energy
   4. Electrical energy
   Show answer

   Answer: B. Potential energy

   When a spring is stretched or compressed, its shape is altered, and this stored energy due to its position or configuration is called potential energy. Specifically, it's elastic potential energy.

2. Which of the following is a form of potential energy?

   1. A moving train
   2. A stretched rubber band
   3. A singing bird
   4. A flowing river
   Show answer

   Answer: B. A stretched rubber band

   A stretched rubber band stores elastic potential energy due to its deformed state. A moving train and a flowing river have kinetic energy. A singing bird possesses energy from the sound it produces, which is a form of energy, but the primary energy source for singing is usually chemical energy from food converted into mechanical energy of vocal cords, and then sound energy.

3. Work is done when:

   1. A force is applied, but there is no movement.
   2. A force is applied, and there is movement in any direction.
   3. A force is applied, and there is movement in the direction of the force.
   4. There is movement, but no force is applied.
   Show answer

   Answer: C. A force is applied, and there is movement in the direction of the force.

   In physics, work is defined as the product of the force applied to an object and the displacement of the object in the direction of the force. If there is no movement, or movement is perpendicular to the force, no work is done.

4. A bow is drawn back. What type of energy is stored in the drawn bow?

   1. Kinetic energy
   2. Magnetic energy
   3. Elastic potential energy
   4. Chemical energy
   Show answer

   Answer: C. Elastic potential energy

   Drawing back a bow deforms it, storing energy in its stretched material. This stored energy is elastic potential energy.

5. A stretched rubber band has potential energy. If it snaps and hits a wall, what energy transformation occurs?

   1. Potential to chemical
   2. Kinetic to potential
   3. Potential to kinetic and sound
   4. Thermal to kinetic
   Show answer

   Answer: C. Potential to kinetic and sound

   The stored potential energy in the stretched rubber band is converted into kinetic energy as it moves and then into sound energy upon impact with the wall.
