Which equation is used to calculate the weight of an object on a planet?
2 answers:
W=mg
Explanation:
the weight of an object on a planet is given by the law:
where
m is the mass of the object
g is the value of the gravitational acceleration on the planet
While the mass of the object, m, depends only on the properties of the object (so, it is the same on every planet), the weight W, depends on the value of g, which is different from planet to planet, therefore the weight of an object changes if we move it to another planet.

Conduction occurs through direct physical contact. Heat transferred from the pot to the handle, and from the handle to the hand, are both examples of conduction.
