mass weight newtons kilograms gravity
the ________ of an object stays the same wherever you take it. it is measured in ______. the ______ of an object is due to the pull of ______. it changes depending on where the object is. it is measured in ________

1. homer says he weighs 130kg. what should he say? (1)
2. there is a relationship between mass and weight. use the equation below to calculate the weight of each object.

weight = mass x gravitational field strength or w = m x g
a) dudley the donkey, mass 125kg (2) b) tanya the tortoise, mass 15kg (2)

Explanation:

1.

Step1: Definir masa

La masa de un objeto es constante y se mide en kilogramos.
La masa de un objeto stays the same wherever you take it. It is measured in kilogramos.

Step2: Definir peso

El peso es debido a la atracción gravitacional y se mide en newtons.
The peso of an object is due to the pull of gravedad. It changes depending on where the object is. It is measured in newtons.

El término correcto es masa cuando se refiere a 130 kg. El peso se expresa en newtons.

Step1: Calcular el peso de Dudley

Usamos la fórmula $w = m\times g$, suponiendo $g = 9.8\ m/s^{2}$ (valor estándar en la superficie de la Tierra).
$m = 125\ kg$, entonces $w=125\times9.8 = 1225\ N$.

Step2: Calcular el peso de Tanya

Usamos la misma fórmula $w = m\times g$ con $m = 15\ kg$.
$w = 15\times9.8=147\ N$.

Answer:

The masa of an object stays the same wherever you take it. It is measured in kilogramos. The peso of an object is due to the pull of gravedad. It changes depending on where the object is. It is measured in newtons.
