Kinetic Energy Vs Potential Energy | Kinetic and potential energy ... - Free Printable

Explanation:
We are given a worksheet titled “Energy Transformations.” The goal is to match each picture pair (left → right) with the correct energy transformation using the word bank:

Word Bank:
- Kinetic
- Potential
- Sound
- Mechanical
- Light
- Elastic
- Radiant
- Chemical
- Electrical
- Stored
- Nuclear
- Heat

Let’s go row by row.

Row 1:
Left: A hand plugging in a lamp (electricity being supplied).
Right: A lit lamp (producing light and some heat).
→ Input energy: Electrical (from the outlet).
→ Output energy: Light (and some heat, but the main visible output is light; “Light” is in the word bank).
So: Electrical → Light

Row 2:
Left: A plate of food (e.g., apple, bread — food stores energy).
Right: A boy running (movement = kinetic energy).
→ Food contains Chemical energy (stored in bonds).
→ When digested, it becomes energy for movement → Kinetic energy.
So: Chemical → Kinetic

Row 3:
Left: The Sun (gives off sunlight).
Right: A person sweating/feeling hot (heat energy).
→ Sun emits Radiant energy (light and infrared — radiant includes visible light and heat radiation).
→ When absorbed by skin, it becomes Heat.
Note: “Radiant” is in the word bank; “Heat” is also there.
So: Radiant → Heat

Row 4:
Left: Two batteries (store chemical energy, but when used, they produce electrical energy).
Right: A boombox playing music (sound + maybe light, but mainly sound).
→ Batteries provide Electrical energy.
→ Boombox converts that into Sound (and some heat, but sound is the key output shown).
So: Electrical → Sound

Wait — but Row 1 already used Electrical → Light. Can Electrical be used twice? Yes — the word bank lists words, not limited-use tokens. The task says “write the words in the correct place,” meaning each blank gets one word — input on left, output on right. So reusing words is allowed if appropriate.

But let’s double-check Row 4: Are batteries *chemical* to *electrical*? Actually, batteries store Chemical energy and convert it to Electrical energy. Then the boombox converts electrical to sound. However, the left image shows just the batteries (not connected), so likely the transformation shown is from battery energy → boombox output. Since the boombox is powered by the batteries, the full chain is Chemical → Electrical → Sound, but the diagram shows only one arrow: left image → right image. So we need the *initial* form in the left box and *final* form in the right box.

In educational worksheets like this, they usually simplify:
- Batteries = Chemical energy stored.
- Boombox playing = Sound energy produced.

But is Chemical → Sound acceptable? Technically, it skips electrical, but many curricula accept that for simplicity.

Let’s cross-check common standards:

- Food → movement = Chemical → Kinetic ✔ widely accepted
- Sun → warmth = Radiant → Heat ✔
- Plug in lamp = Electrical → Light ✔
- Battery-powered radio: often labeled as Chemical → Sound or Chemical → Electrical → Sound, but since only one step is drawn, and the left is *batteries*, right is *speaker/sound*, most worksheets use Chemical → Sound.

However, look at the word bank: It includes both Chemical and Electrical, and also Stored. “Stored” is vague — usually not used as a type of energy, but as a descriptor (e.g., stored chemical energy). Better to avoid “Stored” unless clearly indicated.

Another clue: In Row 2, food is clearly Chemical. So batteries should also be Chemical (since both are stored chemical energy sources).

Thus:
Row 4: Chemical → Sound

But wait — now we have two rows using Chemical as input (Row 2 and Row 4). Is that okay? Yes — multiple things can be chemical energy sources.

Let’s list all four transformations clearly:

1. Plugging lamp: Electrical → Light
2. Eating food → running: Chemical → Kinetic
3. Sun → feeling hot: Radiant → Heat
4. Batteries → boombox sound: Chemical → Sound

Now verify all words used are in the bank:
- Electrical ✔
- Light ✔
- Chemical ✔
- Kinetic ✔
- Radiant ✔
- Heat ✔
- Sound ✔

All good.

One more check: Could Row 3 be “Light → Heat”? But the Sun emits *radiant* energy (which includes visible light and infrared); “Radiant” is the precise term in the bank, and “Light” is separate. Since “Radiant” is listed, and the Sun is the classic example of radiant energy source, we use Radiant → Heat.

Final assignments:
Row 1 left: Electrical | right: Light
Row 2 left: Chemical | right: Kinetic
Row 3 left: Radiant | right: Heat
Row 4 left: Chemical | right: Sound

Yes — this matches standard elementary science expectations.

Final Answer:
Electrical, Light, Chemical, Kinetic, Radiant, Heat, Chemical, Sound
