Title: Escape Velocity Earth Desc
Course: Physics copy 1

Q: A rocket will be able to escape the Earth's gravity if its kinetic energy near the surface of the earth plus the gravitational potential energy equals zero. The escape velocity from earth for an object of any mass would be _____ km/s. (enter your answer correct to 3 sig digs)
A: 11.2 (± 0.3)

Q: A larger object will require more velocity to escape the gravity of a planet.
- True (When kinetic energy and potential energy are equated, the masses will cancel)
- False
A: False

Q: A larger object will require more kinetic energy to escape the gravity of a planet.
- True
- False (Yes, potential energy is proprotional to mass)
A: True
