Class 11 Physics simulations · Gravitation

Escape from a planet

Explore escape speed for planets with different mass and radius.

Open the simulation

What to notice

Escape speed is independent of the mass of the launched object.

Key relation

vesc = √(2GM/R)

Try this

Double planet radius at fixed mass.

What you can change

• Planet mass: 0.2 to 3 Earth masses
• Planet radius: 0.5 to 2 Earth radii
