Question

using the law of conservation of energy ,obtain the expression for the escape velocity. ​

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.

Answer 2

Answer:

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

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

2)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.
