Sample Problems and Solutions from the Gizmo Answer Key
Problem 1: Calculating Gravitational Force
Scenario: Two objects, with masses 5 kg and 10 kg, are separated by a distance of 3 meters. Calculate the gravitational force between them.
- Identify known variables: m1 = 5 kg, m2 = 10 kg, r = 3 m
- Use Newton's Law: F = G (m1 m2) / r^2
- Insert values: F = 6.674 × 10^-11 N·(m^2/kg^2) (5 10) / 3^2
- Calculate numerator: 6.674 × 10^-11 50 = 3.337 × 10^-9
- Calculate denominator: 9
- Final force: F = 3.337 × 10^-9 / 9 ≈ 3.708 × 10^-10 N
Answer: The gravitational force between the two objects is approximately 3.708 × 10^-10 Newtons.
Problem 2: Effect of Increasing Distance
Scenario: How does doubling the distance between two objects affect the gravitational force?
- Recall the inverse-square law: F ∝ 1 / r^2
- Original force: F1
- New distance: 2r
- New force: F2 = F1 / (2)^2 = F1 / 4
Conclusion: Doubling the distance reduces the gravitational force to one-quarter of its original value.
