Lesson: Escape SpeedPhysics
In this lesson, we will learn how to calculate the vertical speed that an object must have in order to escape the gravitational pull of a planet.
Sample Question Videos
Earth has a mass of kg and a radius of 6,370 km. Calculate the escape speed of Earth. Give your answer to one decimal place.
Triton is the largest moon of Neptune with a mass of kg and a radius of 1,350 km. What is the escape speed of Triton? Give your answer to the nearest meter per second.
Earth has a mass of kg and a radius of 6,370 km. Calculate the ratio of the escape speed on the surface of Earth to the escape speed 20 km above the surface of Earth. Give your answer to five decimal places.
