Understanding Weight vs. Mass
* Mass is the amount of matter in an object. It's measured in kilograms (kg).
* Weight is the force of gravity acting on an object's mass. It's measured in Newtons (N).
Formula:
Weight (W) = Mass (m) × Acceleration due to gravity (g)
* g (acceleration due to gravity on Earth) ≈ 9.8 m/s²
Calculation:
W = 75 kg × 9.8 m/s²
W = 735 N
Therefore, the weight of a man with a mass of 75 kg is approximately 735 Newtons.
