List examples of when the kinetic energy of particles would be increasing

Answer 1

1. When an external force is applied to a system, causing the particles to move faster.
2. During a chemical reaction where energy is released and the particles gain kinetic energy.
3. When heat is added to a system, causing the particles to vibrate more vigorously.
4. When an object is falling due to gravity, its kinetic energy increases as it gains speed.
5. During a phase change from a solid to a liquid or gas, the kinetic energy of the particles increases as they gain more freedom of movement.
