Question: What is the effect of increasing the height of a satellite on its orbital speed?

Options:

Correct Answer: Decreases speed

Solution:

Increasing the height of a satellite decreases its orbital speed, as the gravitational force acting on it decreases.

What is the effect of increasing the height of a satellite on its orbital speed?

Step 1: Understand that a satellite orbits a planet due to gravity.
Step 2: Recognize that the gravitational force decreases as the satellite moves higher from the planet's surface.
Step 3: Realize that the orbital speed is the speed needed to stay in orbit without falling back to the planet.
Step 4: Know that if the gravitational force is weaker (because the satellite is higher), the satellite does not need to move as fast to stay in orbit.
Step 5: Conclude that increasing the height of the satellite results in a decrease in its orbital speed.
