Question

what is the weight of a 1kg mass object on planet earth? 5 newtons 1 pound 9.8 newtons 9.8 pounds 1 newton

Explanation:

Step1: Recall weight - mass formula

Weight \(W = mg\), where \(m\) is mass and \(g\) is acceleration due to gravity on Earth (\(g = 9.8m/s^{2}\)).

Step2: Substitute values

Given \(m = 1kg\) and \(g=9.8m/s^{2}\), then \(W=1kg\times9.8m/s^{2}=9.8N\).

Answer:

C. 9.8 Newtons
