10. The Earth’s escape speed (the speed you need to get away forever) is about 25,000 miles per hour. Escape speed depends on the gravity of the object trying to hold the spacecraft from escaping. Based on your understanding of gravity, how will the escape speed from the Moon compare to the escape speed from Earth?
a. The Moon’s escape speed will be greater than Earth’s
b. The Moon’s escape speed will be smaller than Earth’s
c. The Moon’s escape speed will be exactly the same as Earth’s
d. The Moon’s escape speed will change depending on whether it’s a crescent Moon or a full Moon
e. The Moon’s escape speed will be balanced by the Earth being so close and it will be zero
