Weight of an Object on Earth

To find the weight of an object, we use the formula:

$Weight=Mass\times Gravity\backslash text\{Weight\}\; =\; \backslash text\{Mass\}\; \backslash times\; \backslash text\{Gravity\}$

Weight=Mass×Gravity

Given Information

• Mass of the object: 20 kg
• Gravity on Earth: Approximately
  $9.8\hspace{0.17em}{2}^{}9.8\; \backslash ,\; \backslash text\{m/s\}^2$ 

  9.8m/s2

Calculation

1. Formula Application:

   $Weight=20\hspace{0.17em}kg\times 9.8\hspace{0.17em}{2}^{}=196\hspace{0.17em}N\backslash text\{Weight\}\; =\; 20\; \backslash ,\; \backslash text\{kg\}\; \backslash times\; 9.8\; \backslash ,\; \backslash text\{m/s\}^2\; =\; 196\; \backslash ,\; \backslash text\{N\}$Weight=20kg×9.8m/s2=196N

2. Result:
   • The weight of the object on Earth is 196 Newtons (N).

Summary

• An object with a mass of 20 kg will weigh 196 N on Earth due to the force of gravity acting on it. This weight is what you feel when lifting or supporting the object.
