Here's why:
* Weight vs. Force: Weight is a force, specifically the force of gravity acting on an object's mass.
* Newton's Second Law: This law states that force (F) is equal to mass (m) multiplied by acceleration (a): F = ma.
* Gravity: The acceleration due to gravity (g) is approximately 9.8 m/s².
Therefore:
* Weight = Mass x Acceleration due to gravity (W = mg)
* A heavier object has more mass, resulting in a larger weight (force) due to gravity.
Example:
* A 10 kg object weighs 10 kg x 9.8 m/s² = 98 Newtons (N).
* A 5 kg object weighs 5 kg x 9.8 m/s² = 49 Newtons (N).
Conclusion:
The heavier object (10 kg) exerts a greater downward force (98 N) than the lighter object (5 kg) which exerts a force of 49 N.
