To calculate weight from gravity, use the formula: Weight = Mass × Gravitational Acceleration. Here, mass (m) is in kilograms (kg) and gravitational acceleration (g) is approximately 9.8 m/s² on Earth. For example, a 10 kg object weighs 98 Newtons on Earth (10 kg × 9.8 m/s²). This formula helps determine the force exerted on an object due to gravity.

FAQs & Answers

  1. What is the formula to calculate weight from gravity? The formula to calculate weight is Weight = Mass × Gravitational Acceleration. Here, mass is in kilograms and the gravitational acceleration is typically 9.8 m/s² on Earth.
  2. How does gravitational acceleration vary across planets? Gravitational acceleration varies depending on the planet's mass and radius. For example, it is about 9.8 m/s² on Earth, 3.7 m/s² on Mars, and 24.8 m/s² on Jupiter.
  3. What units are used for weight and mass? Weight is measured in Newtons (N), while mass is measured in kilograms (kg).
  4. Can weight be different in different locations? Yes, weight can change based on gravitational force, which can vary with location (e.g., altitude, latitude). For instance, an object weighs slightly less at the equator than at the poles due to Earth's shape and rotation.
