Question

which equation is used to calculate the weight of an object on a planet?
○ ( w = mg )
○ ( w = mg )
○ ( w = \frac{m}{g} )
○ ( w = \frac{m}{g} )

Explanation:

Weight (\( w \)) of an object is the force due to gravity. The formula \( w = mg \) is used, where \( m \) is mass and \( g \) is the acceleration due to gravity on the planet. \( G \) is the gravitational constant (not for weight - calculation on a planet's surface), and the other options (\( w=\frac{m}{g} \), \( w = \frac{m}{G} \)) do not represent the weight - force relationship.

Answer:

A. \( w = mg \)
