Explanation

When a satellite orbits close to the Earth's surface, it must travel faster to avoid falling towards the Earth due to gravity. This means its speed is maximum.

Since kinetic energy (KE) is proportional to the square of the speed (v), the kinetic energy will also be maximum:

KE = (1/2)mv^2

where m is the mass of the satellite.

So, when a satellite orbits close to the Earth's surface, its kinetic energy will be maximum.
