Question 1

What is the formula for calculating escape velocity?

v = √(GM/r)
v_esc = √(2GM/r)
v = GM/r^2

💡 Hint: Look for the formula that includes a square root and double G.

Question 2

True or False: A Hohmann transfer orbit is a method to move from a higher orbit to a lower one only.

True
False

💡 Hint: Think about what a transfer orbit does.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A satellite needs to transport from a low Earth orbit (radius = 7,000 km) to a geostationary orbit (radius = 42,164 km). Calculate the required Δv for the Hohmann transfer.

💡 Hint: Use the formula: v = √(GM/r) for velocity.

Challenge 2 Hard

Calculate how much energy is required to launch a satellite of 1000 kg to escape velocity on Earth. Use v_esc = √(2GM/r).

💡 Hint: Don't forget to calculate the escape velocity using G, M, and r first.
