Across
- 3. gravitational constant (G) is a fundamental physical constant that quantifies the strength of gravity
- 4. r usually refers to radial distance or radius in physics/math
- 5. Law of Universal Gravitation states that every mass in the universe attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers
- 10. force is any force that pulls two or more objects, particles, atoms, or molecules toward each other
- 11. Square Law is a fundamental physics principle stating that the intensity of a force or radiation
- 12. is the fundamental force of attraction between any two objects with mass
- 13. refers to the force of gravity on an object's mass
- 14. is a fundamental property of matter, representing its inertia (resistance to acceleration) and often seen as the amount of "stuff" in an object, measured in kilograms (kg) in the SI system
- 15. Velocity is the minimum speed an object needs to break free from a celestial body's gravity (like Earth or the Moon) without further propulsion
Down
- 1. of mass is the average position of all the parts of an object or system, weighted by their masses
- 2. field is the influence a massive object extends into space
- 6. is the curved, repeating path an object takes around another due to gravity
- 7. force (\(F\)) is the attractive pull between any two masses, described by Newton's Law of Universal Gravitation: \(F=G\frac{m_{1}m_{2}}{r^{2}}\)
- 8. fall in physics is the motion of an object where gravity is the only force acting on it
- 9. force is the center-seeking force that pulls an object towards the center of a curved path, causing it to move in a circle or arc instead of a straight line
