Across
- 4. the region of space around a massive object where gravity exerts a forc
- 5. the minimum speed an object needs to break free from a celestial body's gravitational pull and travel infinitely far away without further propulsion
- 8. the measure of the force of gravity on an object, calculated by multiplying the object's mass by the acceleration due to gravity
- 9. the curved path an object takes around another object due to their mutual gravitational attraction
- 13. a law stating that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers
- 14. centripetal force is the center-seeking force that makes an object move in a curved or circular path, always directed towards the center of that curve, perpendicular to the object's velocity, and calculated as \(F_{c}=mv^{2}/r\)
- 15. the amount of "stuff" in an object and its resistance to changes in motion (inertia), measured in kilograms (kg)
Down
- 1. fundamental physical constant that quantifies the strength of gravity, representing the force between two unit masses separated by a unit distance
- 2. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
- 3. the universal attractive force between any two objects with mass or energy, pulling them toward each other
- 6. any force that pulls two or more objects, particles, or masses toward each other, drawing them closer together
- 7. physical quantity's intensity (like light, gravity, or sound) is inversely proportional to the square of the distance from its source
- 10. free fall is the motion of an object where gravity is the only force acting upon it
- 11. radial distance from a central point or between centers of masses
- 12. the average position of all the mass in an object or system
