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 rate at which objects accelerate towards the Earth's center. On Earth, it's approximately 9.8 m/s².
Formula
The relationship between weight (W), mass (m), and acceleration due to gravity (g) is:
W = m * g
Solving for Mass
To find the mass (m), we can rearrange the formula:
m = W / g
Calculation
1. Weight (W): 19.6 N
2. Acceleration due to gravity (g): 9.8 m/s²
m = 19.6 N / 9.8 m/s²
m = 2 kg
Answer: The mass of the object is 2 kilograms.
