when an object reaches max height is ek or eg 0 or neither

When an object reaches its maximum height, its kinetic energy (KE) is zero, while its gravitational potential energy (PE) is at its maximum. Therefore:

- **Kinetic Energy (KE)**: 0 (the object is momentarily at rest at the highest point)
- **Gravitational Potential Energy (PE)**: Maximum (due to the height above the reference point)

If you're considering the total mechanical energy of the system (sum of KE and PE), it remains constant (assuming no air resistance or other dissipative forces).

If you have more specific questions or need further clarification, feel free to ask!

### Follow-Up Questions
1. How is kinetic energy calculated?
2. What factors affect gravitational potential energy?
3. How do you determine the maximum height reached by a projectile?
4. What happens to energy as the object falls back down?
5. Can energy be converted from one form to another in this context?

### Tip
Remember that the total mechanical energy of an ideal system (without friction) is conserved.
