Question

1. what does this equation mean?

to calculate an objects weight, you multiply the objects mass by _____, and then add _____.

1. how does this equation show that an objects weight is equal to its mass multiplied by gravitational acceleration ($f_g = mg$)?

a. looking at our above equation, weight = slope * _______.

b. the slope of our line is around 9.8 n/kg. in our previous lab, we learned that the value of gravitational acceleration on earth is _______ m/s².

c. so, the slope of our line represents earths gravitational _______.

d. plugging into weight = slope mass, weight = _______ acceleration mass.

1. if an objects mass is 1 kg, what is its weight on earth? plug the appropriate values into the below equation to solve for weight, $f_g$.

$f_g = mg$

1. if an objects mass is 5 kg, what is its weight on earth? plug the appropriate values into the below equation to solve for weight, $f_g$.

$f_g = mg$

Explanation:

Question 7

Step1: Recall weight formula

Weight ($W$) is related to mass ($m$) by the formula $W = mg$, where $g$ is gravitational acceleration (no addition, so add 0).

Step2: Fill in blanks

Multiply mass by gravitational acceleration (≈9.8 m/s² or N/kg), add 0.

Step1: Relate to weight formula

From \(W = mg\) (or weight = slope * mass), the blank is "mass".

Step1: Recall Earth's \(g\)

Gravitational acceleration on Earth is approximately \(9.8 \, \text{m/s}^2\).

Answer:

To calculate an object’s weight, you multiply the object’s mass by \(\boldsymbol{\text{gravitational acceleration (or } 9.8 \, \text{N/kg)}}\), and then add \(\boldsymbol{0}\).
