Episode 5 — Potential & Kinetic Energy

Energy Transfers

Learners will be able to:

• Describe an energy transfer in terms of input energy, transfer and output energy. • Distinguish between energy transferred within an object and energy transferred between objects. • Trace a chain of energy transfers through a system (e.g. food to muscle to arm to object). • Explain that some energy is lost from a system as heat energy during a transfer (wasted energy). • Describe the energy transfers occurring in real-life examples such as a soccer kick, a game of pool or table tennis, and a swinging pendulum.
