Across
- 1. a force that opposes the relative motion of two surfaces in contact, whether sliding or attempting to slide
- 4. the property of matter that causes an object to resist changes in its state of motion
- 8. the pulling force exerted by a string, rope, cable, or similar flexible connector when it is pulled tight from opposite ends
- 9. a push or pull on an object resulting from an interaction between two objects
- 10. the force of attraction between any two objects with mass
- 13. occurs when multiple forces acting on an object are equal in magnitude (strength) and opposite in direction, resulting in a net force of zero
- 14. the single, overall force that results from all the individual forces acting on an object simultaneously, calculated as the vector sum of these forces
- 15. a moving object's "quantity of motion," calculated as the product of its mass and its velocity
Down
- 2. the standard unit of force, equal to the force required to accelerate a mass of one kilogram at a rate of one meter per second squared
- 3. occurs when the total force (or net force) acting on an object is not zero, meaning the forces are not equal in magnitude or opposite in direction
- 5. Force a push or a pull exerted on an object by another object or person, typically through direct contact
- 6. the scientific study of the Earth's crust and the large-scale processes, such as plate movement, that deform it, leading to features like mountains, volcanoes, and earthquakes
- 7. the rate of change of an object's velocity—its speed and direction—over time
- 11. the amount of matter contained within an object, which determines its inertia, or its resistance to changes in motion
- 12. the speed of an object in a specific direction
