Here's a breakdown:
* Gravity: Earth exerts a force of attraction on all objects, including your body. This force is called gravity.
* Weight: Weight is the force of gravity acting on your mass. It's measured in units of force, such as Newtons (N) or pounds (lbs).
* Mass: Mass is the amount of matter in your body. It's measured in units of kilograms (kg) or pounds (lbs).
How to calculate your weight:
Weight (W) = Mass (m) x Acceleration due to gravity (g)
* g is approximately 9.8 m/s² on Earth's surface.
Example:
If your mass is 70 kg, your weight would be:
W = 70 kg x 9.8 m/s² = 686 N
Important Note:
While weight is the force of gravity acting on your body, it's often mistakenly used interchangeably with mass. However, mass is a fundamental property of matter, while weight depends on the gravitational field. For example, your mass stays the same on the moon, but your weight would be significantly lower because the moon's gravity is weaker.
