Universal Gravitation

Universal gravitation states that every mass attracts every other mass with a force F = G(m₁m₂)/r². It's crucial for understanding planetary motions and satellite orbits. ScanSolve helps break down these calculations step-by-step.

How to Approach Universal Gravitation

Identify two masses and distance

Find the masses of the two objects and the distance between their centers (e.g. Earth and Moon).

Input data into gravitation formula

Use F = G(m₁m₂)/r², inputting mass values and distance to calculate force.

Analyze gravitational impact

Review calculated force to understand effects on movement or orbit.

What is gravity?

Gravity is the force that attracts two bodies toward each other, with its strength depending on their masses and the distance between them.

Frequently Asked Questions

What is the gravitational constant G?+

G ≈ 6.674×10⁻¹¹ N(m/kg)², a universal constant used in the gravitational force equation.

How does distance affect gravitational force?+

Gravitational force decreases with the square of the distance between two objects, following the inverse-square law.

Can universal gravitation apply to all objects?+

Yes, the law applies universally but is most impactful for massive objects like planets and stars.
