Question

1. what factor determines the escape velocity for an object?

resistance
volume
mass
shape

Explanation:

Escape velocity is derived from gravitational potential energy balance, given by \( v_e = \sqrt{\frac{2GM}{r}} \), where \( G \) is the gravitational constant, \( M \) is the mass of the celestial body, and \( r \) is its radius. The object's own resistance, volume, or shape does not affect this velocity; only the mass of the body it is escaping from (and the radius) matters. Among the options, "mass" refers to the relevant factor (the celestial body's mass).

Answer:

mass
