⚠️ Common Misconceptions
Misconception 1: "Energy is used up or destroyed when something stops moving"
Energy is NEVER destroyed. When a moving object stops due to friction or air resistance, its kinetic energy transfers to the thermal store of the surroundings. The total energy is conserved — it has just spread out (dissipated) into the surroundings, making them very slightly warmer.
Misconception 2: "Heat and thermal energy are the same thing"
Heat is a transfer of energy — it is a process, not a store. Thermal energy is what is stored in an object due to the random kinetic energy of its particles. You should say "the thermal energy store of the object increases" rather than "the object gains heat".
Misconception 3: "Gravitational potential energy only applies to objects in the air"
Any object with mass has GPE relative to some reference point. Even an object resting on a table has GPE relative to the floor. What matters is the height change — climbing stairs, a ball being thrown upward, a lift going up: all involve changes in GPE.
