Understanding the Concepts
* Weight: The force of gravity acting on an object's mass. It's measured in Newtons (N).
* Mass: The amount of matter in an object. It's measured in kilograms (kg).
* Acceleration due to gravity (g): The constant acceleration experienced by objects falling freely near the Earth's surface. It's approximately 9.8 m/s².
Formula
Weight (W) = Mass (m) × Acceleration due to gravity (g)
Calculation
1. Rearrange the formula to solve for mass:
m = W / g
2. Plug in the given values:
m = 49 N / 9.8 m/s²
3. Calculate the mass:
m = 5 kg
Answer: The mass of the object is 5 kilograms.
