1. Explain the law of universal gravitation in your own words, including the significance of the variables in the formula F = G(m₁m₂/r²).
2. Calculate the gravitational force between two objects with masses of 5 kg and 10 kg that are 2 meters apart. Use G = 6.67 × 10⁻¹¹ N m²/kg² in your calculation.
3. If the distance between two objects is doubled, how does that affect the gravitational force between them? Explain your reasoning based on the formula F = G(m₁m₂/r²).
