Weight Physics Example 2

Follow the full solution, then compare it with the other examples linked below.

Example 2

medium
An object weighs 196 N196 \text{ N} on Earth. What is its mass? Use g=9.8 m/s2g = 9.8 \text{ m/s}^2.

Solution

  1. 1
    Use W=mgW = mg and rearrange: m=Wgm = \frac{W}{g}.
  2. 2
    m=1969.8=20 kgm = \frac{196}{9.8} = 20 \text{ kg}

Answer

m=20 kgm = 20 \text{ kg}
Weight and mass are related through the gravitational acceleration. Knowing the weight on a planet allows us to calculate the mass.
