Detailed Solution
Download Solution PDFThe correct answer is 29.4 N.
Key Points
- The mass of the football is given as 3 kg.
- The acceleration due to gravity on Earth is 9.8 m/s².
- Weight is calculated using the formula: Weight (W) = Mass (m) × Acceleration due to gravity (g).
- Substituting the values, W = 3 kg × 9.8 m/s².
- The weight of the football on Earth is 29.4 N.
Additional Information
- Mass and Weight:
- Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).
- Weight is the force exerted by gravity on an object, measured in Newtons (N).
- Gravitational Force:
- Gravitational force is the attractive force between two masses.
- On Earth, this force is quantified as 9.8 m/s².
- Formula for Weight:
- The formula to calculate weight is W = m × g.
- Here, W represents weight, m represents mass, and g represents the gravitational force.
- Importance of Gravity:
- Gravity keeps planets in orbit around the sun.
- It gives weight to physical objects and is responsible for the free fall of objects.
