The escape velocity (v_e) is the minimum velocity an object must have in order to break free from a planet's gravitational influence without further propulsion. It is derived from the balance between the object's kinetic energy and the planet's gravitational potential energy. The formula for escapeRead more
The escape velocity (v_e) is the minimum velocity an object must have in order to break free from a planet’s gravitational influence without further propulsion. It is derived from the balance between the object’s kinetic energy and the planet’s gravitational potential energy.
The formula for escape velocity is:
v_e = √(2GM / R)
Where:
– v_e is the escape velocity,
– G is the gravitational constant (6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²),
– M is the mass of the planet,
– R is the radius of the planet.
From this formula, we can see that escape velocity depends on the mass of the planet (M) in a square root relationship. Specifically, the escape velocity increases with the square root of the mass. This means that for a planet with greater mass, the escape velocity will be higher.
Example:
– A planet with a higher mass will have a higher escape velocity.
– A smaller planet or a planet with lower mass will have a lower escape velocity.
In summary:
– Escape velocity is directly proportional to the square root of the mass of the planet.
