The three phases of a physical encounter are the initial contact, the interaction, and the conclusion.
Step-by-step explanation:
The three phases of a physical encounter are the initial contact, the interaction, and the conclusion.
1. Initial contact: This is where the interaction begins and the two objects come into contact with each other.
2. Interaction: This is the main phase of the encounter where forces are applied and energy is exchanged between the objects.
3. Conclusion: This is the phase where the interaction comes to an end and the objects separate from each other.
