Weight and mass are often used interchangeably in everyday language, but scientifically, they are different. If you have a mass of 230 kg, how much does it weigh in newtons?
Understanding Mass vs. Weight
- Mass (measured in kilograms) is the amount of matter in an object and remains constant regardless of location.
- Weight (measured in newtons) is the force exerted on an object due to gravity and depends on the gravitational pull of the location.
The relationship between weight and mass is given by the formula:
Weight (N)=Mass (kg)×Acceleration due to gravity (m/s2)
On Earth, the standard gravitational acceleration (g) is approximately 9.81 m/s².
Calculating the Weight of 230 kg
Using the formula:
230×9.81=2,255.3 N230
So, an object with a mass of 230 kg weighs about 2,255.3 newtons on Earth.
What If You Were on a Different Planet?
Since weight depends on gravity, the same object would weigh differently on other planets:
- On the Moon (gravity = 1.62 m/s²): 230×1.62=372.6 N230
- On Jupiter (gravity = 24.79 m/s²): 230×24.79=5,701.7 N230
The weight of a 230 kg object on Earth is approximately 2,255.3 N, but this value changes depending on gravity. Understanding this distinction is crucial in physics, engineering, and even space exploration!
