1. Understand the Formula
The force of gravity between two objects is given by Newton's Law of Universal Gravitation:
F = G * (m1 * m2) / r²
Where:
* F is the force of gravity
* G is the gravitational constant (6.674 × 10⁻¹¹ N⋅m²/kg²)
* m1 and m2 are the masses of the two objects
* r is the distance between their centers
2. Plug in the Values
* m1 = 7.0 kg
* m2 = 7.0 kg
* r = 2.0 m
* G = 6.674 × 10⁻¹¹ N⋅m²/kg²
3. Calculate the Force
F = (6.674 × 10⁻¹¹ N⋅m²/kg²) * (7.0 kg * 7.0 kg) / (2.0 m)²
F ≈ 8.2 × 10⁻¹⁰ N
Therefore, the gravitational force between the two bowling balls is approximately 8.2 × 10⁻¹⁰ Newtons.
Important Note: This force is incredibly small. You wouldn't be able to feel it! The force of gravity becomes significant only when at least one of the objects is very massive (like the Earth).
