Question

Calculate escape velocity by using principle of conservation of energy.​

Answer 1

Answer:

This is the escape speed - the minimum speed required to escape a planet's gravitational pull.

• To find the escape velocity, apply energy conservation: Ui + Ki = Uf + Kf

• For a planet of mass M and radius R, the potential energy of an object of mass m at the planet's surface is: U= - G m M/R.
