New Worksheet – Science - Universal Law of Gravitation (II)
1. The gravitational force between two objects (mass 1 = 20 kg, mass 2 = 85 kg) is measured when the objects are 15 centimeters apart. The masses are then changed to mass 1 = 5 kg, mass 2 = 60 kg, and the distance between them is increased to 30 cm. How does the gravitational attraction compare to the first one that was measured?
Answer: _______________________
2. The gravitational force between two objects (mass 1 = 400 kg, mass 2 = 75 kg) is measured when the objects are 100 centimeters apart. The masses are then changed to mass 1 = 45 kg, mass 2 = 5 kg, and the distance between them is changed to 40 cm. How does the gravitational attraction compare to the first one that was measured?
Answer: _______________________
3. The gravitational force between two objects (mass 1 = 75 kg, mass 2 = 40 kg) is measured when the objects are 100 centimeters apart. The masses are then changed to mass 1 = 5 kg, mass 2 = 80 kg, and the distance between them is changed to 90 cm. How does the gravitational attraction compare to the first one that was measured?
Answer: _______________________
4. The gravitational force between two objects (mass 1 = 60 kg, mass 2 = 5 kg) is measured when the objects are 55 centimeters apart.

Answer: _______________________
5. The gravitational force between two objects (mass 1 = 65 kg, mass 2 = 7 kg) is measured when the objects are 80 centimeters apart. The masses are then changed to mass 1 = 40 kg, mass 2 = 49 kg, and the distance between them is changed to 8 cm. How does the gravitational attraction compare to the first one that was measured?
