1. Dropping a ball

Given: Gravitational potential → [ ? ]

✔ Answer: Kinetic

Explanation:
When you hold a ball up high, it has gravitational potential energy because of its position in Earth’s gravity field. When you drop it, that stored energy is converted into kinetic energy — the energy of motion — as the ball accelerates downward.

*(Note: In real life, some energy also becomes thermal or sound due to air resistance and impact, but for this level, we focus on the main transfer.)*

2. Connecting a battery to a circuit

[ ? ] → [ ? ]

✔ Answer: Chemical → Electric

Explanation:
A battery stores energy in the form of chemical energy (from reactions between its internal materials). When you connect it to a circuit, those chemical reactions produce a flow of electrons — that’s electric energy — which powers devices in the circuit.

3. Switching on a light bulb

[ ? ] → [ ? ] + [ ? ]

✔ Answer: Electric → Light + Thermal

Explanation:
When you switch on a light bulb, electric energy flows through the filament (or LED). Most of that energy is converted into light energy (so you can see), but a significant portion also becomes thermal energy (heat) — especially in incandescent bulbs, which get hot. Even LEDs produce some heat.

*(Note: Some bulbs may also produce tiny amounts of sound, but light + thermal are the main outputs.)*

✔ Final Answers:

1. Dropping a ball
Gravitational potential → Kinetic

2. Connecting a battery to a circuit
Chemical → Electric

3. Switching on a light bulb
Electric → Light + Thermal

🌟 Extension Challenge: Come up with your own example!

Example: Stretching a rubber band and letting it snap

Energy Transfer:
Elastic potential → Kinetic + Sound

Explanation:
When you stretch a rubber band, you store elastic potential energy in it. When released, that energy turns into kinetic energy (the band moves quickly), and you often hear a “snap” — that’s sound energy.

*(You could also say “elastic → kinetic + thermal”, since friction generates heat too — both are valid!)*
