Study Notes
Calculations Involving Force, Mass, and Gravity
- Formula: Force (F) = mass (m) × acceleration due to gravity (g)
- Problem 1: An object with a mass of 75 kg on Earth (gravity = 9.8 m/s²) has a weight of 735 N.
- Problem 2: A 1 kg ball falling due to gravity experiences a force of 9.8 N.
- Problem 3: An object weighing 500 N on Earth (gravity = 9.8 m/s²) has a mass of 51.02 kg.
- Problem 4: An astronaut weighing 75 kg on Earth would weigh 120 N on the moon (gravity = 1.6 m/s²).
- Problem 5: A spaceship with a mass of 9000 kg and a weight of 390,000 N on a distant planet has an acceleration due to gravity of 43.33 m/s².
