Why do astronauts in orbit feel weightless?

• There is no gravity in space
• They are too far from Earth
• They are in constant free-fall
• Their mass becomes zero in orbit

What is the relationship between orbital radius and velocity?

• Velocity remains constant regardless of radius
• Velocity decreases with the inverse square root of radius
• Velocity and radius are directly proportional
