A falling object trades gravitational potential energy for kinetic energy; total energy is conserved when losses are accounted for.
当一个定义与可测量或可观察的现象连接起来时，科学才真正容易记住。
Take one idea at a time. If a new word appears, connect it to a concrete object, number or experiment before moving on.
Start with the central idea, then test it against a concrete element or example. A scientific model is useful when we know what it explains — and where its limits are.
