4 cards from this section. Quick, good the night before a test.
What is the escape speed for Earth?
Consider Earth's mass and radius when calculating.
Why is the escape speed for the Moon lower than for Earth?
Think about how mass influences gravity.
What is the escape speed from the surface of Earth?
Remember the famous speed for leaving Earth's atmosphere.
True or False: Escape speed is the same for all celestial bodies.
Think about different planets and their sizes.
A satellite is orbiting Earth at an altitude where the gravitational pull is only half of what it is at Earth’s surface. What is its escape speed compared to that from the surface?
What happens to the escape speed when gravity is halved?
Determine how the escape speed changes if the radius of Jupiter is doubled and its mass remains unchanged.
Remember the inverse relationship between radius and escape speed.
