energy conversion online exercise for - Free Printable

Problem: Fill in the blanks with the correct words using the provided options:

- Potential energy
- Kinetic energy
- Electrical energy
- Heat energy
- Sound energy
- Light energy

Solution:

#### 1. A battery in a flashlight is an example of _______ energy being converted into _______ energy.
- Explanation: A battery stores chemical energy, which is a form of potential energy. When the flashlight is turned on, this stored energy is converted into electrical energy to power the bulb, which then emits light energy.
- Answer:
- First blank: Potential energy
- Second blank: Electrical energy (converted into Light energy by the bulb)

#### 2. Turning on the TV at your house is an example of _______ energy being converted into both _______ and _______ energy.
- Explanation: When you turn on the TV, electrical energy from the power source is converted into multiple forms of energy, including light energy (from the screen) and sound energy (from the speakers).
- Answer:
- First blank: Electrical energy
- Second blank: Light energy
- Third blank: Sound energy

#### 3. A match being lit is an example of _______ energy being converted into _______ energy.
- Explanation: When a match is struck, the friction generates heat energy, which ignites the match head. This combustion process releases heat and light energy.
- Answer:
- First blank: Potential energy (stored in the chemicals of the match head)
- Second blank: Heat energy (and Light energy as a result of combustion)

#### 4. A baseball being hit by a baseball bat is an example of _______ energy being converted into _______ energy.
- Explanation: Before the ball is hit, it has potential energy due to its position or stored energy in the bat's swing. When the bat strikes the ball, this potential energy is converted into kinetic energy, causing the ball to move rapidly.
- Answer:
- First blank: Potential energy
- Second blank: Kinetic energy

#### 5. The sunlight shining on solar panels is an example of _______ energy being converted into _______ energy. This energy is then transferred into _______ energy when we turn on a lamp.
- Explanation: Solar panels convert sunlight (a form of light energy) into electrical energy. When this electrical energy is used to power a lamp, it is converted into light energy.
- Answer:
- First blank: Light energy
- Second blank: Electrical energy
- Third blank: Light energy
